CVSS v3.1 |
| The UsersWP WordPress plugin before 1.5.10 does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account, allowing unauthenticated attackers to log in as any user, including administrators, whose email address they can assert through a provider account of their own. |
| In the Linux kernel, the following vulnerability has been resolved:
mailbox: riscv-sbi-mpxy: validate RPMI notification lengths
The SBI return value controls how many bytes are copied from shared
memory into the RPMI notification buffer. It is not validated against
the negotiated shared-memory size before that copy. The event walker
also uses a reversed loop condition and can inspect a short event record.
Validate the complete notification length before copying it, iterate only
while a full event header remains, and stop when a declared event payload
extends beyond the copied notification data. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: smbdirect: destroy QP before mem pools on accept failure
On the rdma_accept_failed error path of
smbdirect_accept_connect_request(), the receive io posted just above is
owned by the QP (recv_io is set to NULL after a successful post). The
error path fell through to smbdirect_connection_destroy_mem_pools()
before smbdirect_connection_destroy_qp(), so the mem pools and the
recv_io slab cache were destroyed while that recv_io was still
outstanding on the QP.
The drain in smbdirect_connection_destroy_qp() (ib_drain_qp()) is what
runs the recv completion that returns the recv_io to the free list, so
destroying the pools first leaves the object outstanding at
kmem_cache_destroy() time ("Slab cache still has objects") and later
frees it into an already-destroyed mempool (mempool_free_bulk
NULL-pointer dereference).
Give rdma_accept_failed its own teardown that drains the QP first, then
destroys the mem pools, and returns. The remaining labels
(post_recv_io_failed onward) run before the recv_io was ever posted, so
they keep the mem-pools-then-qp order.
The outstanding recv_io at kmem_cache_destroy() time:

IB/isert: delay the final Login Response until the session is registered
isert_put_login_tx() puts the final Login Response on the wire before
__transport_register_session(), which iscsi_post_login_handler() reaches
only after iscsi_target_do_login() returns. An initiator that issues a

Delay the final Login Response instead. isert_get_rx_pdu() runs from
iscsi_target_rx_thread() after conn->rx_login_comp, completed by
iscsi_post_login_handler() after __transport_register_session(); iscsi-TCP
and cxgbit already take PDUs from that thread, isert alone does not. The
buffers are still posted first, so the initiator's first command does not
meet an empty receive queue and nothing depends on RNR flow control, and
the header and payload live in isert_conn, not in the struct iscsi_login
that iscsi_target_nego_release() frees first.
Over rxe, 400 login cycles per run, the oops appeared in 10 of 20
unpatched runs and in none of 20 runs with this patch. An
initiator that never waits is handled by the next patch.

| In the Linux kernel, the following vulnerability has been resolved:
iommu/dma: Check atomic pool allocation result directly
The non-blocking, non-coherent allocation path uses dma_alloc_from_pool(),
which returns the allocated page and fills cpu_addr only on success.
Do not rely on cpu_addr to detect allocation failure in this path. Check
the returned page directly before using it for the IOMMU mapping. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix integer overflow of user QP buffer size
set_user_buf_size() computes the QP buffer size by left-shifting the
user-supplied rq.wqe_cnt and rq.wqe_shift values as signed integers.
A sufficiently large rq.wqe_cnt causes signed integer overflow, which
is undefined behavior, and yields a small or negative buf_size, causing
ib_umem_get() to map a buffer smaller than the hardware will actually
write into.
Replace the shifts and addition with check_shl_overflow() and
check_add_overflow(), rejecting invalid user inputs.
Moreover, guard the identical shift computing qp->sq.offset in
_create_user_qp() before set_user_buf_size() is reached. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/pm/powerplay: bounds-check voltage index in SMU7 lookup
vddInd and vddcInd fields from VBIOS-parsed tables are used to index into
voltage lookup tables without a bounds check. Return -EINVAL when any
index is out of range. |
| FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS loader assigns file-controlled wsmp.loop_start and wsmp.loop_length values to samples without calling fluid_sample_validate() or fluid_sample_sanitize_loop(). A crafted DLS file can place sample loop points beyond the sample buffer, causing out-of-bounds reads during audio rendering, undefined behavior, possible memory disclosure, and denial of service. Builds compiled with the CMake option enable-native-dls set to OFF do not expose the affected parser. This issue is fixed in version 2.5.6. |
| The Quill Forms | Conversational Multi Step Forms, Surveys & quizzes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Multiple Choice 'Other' Value in all versions up to, and including, 5.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected script executes in the context of the WordPress admin results view, making administrators the primary target when reviewing submitted form entries. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: reject out-of-range evcn in mi_enum_attr()
In mi_enum_attr(), the start/end VCN validation for non-resident
attributes is:
if (svcn > evcn + 1) goto out;
When evcn is U64_MAX the "evcn + 1" expression wraps to 0 and any svcn
passes the check. For evcn values close to U64_MAX (but not equal to it)
the right-hand side is still a meaningless near-wrap upper bound, so a
malformed on-disk attribute with svcn == 0 and evcn near U64_MAX can pass
mi_enum_attr() unrejected.
VCN (virtual cluster number) is a cluster index, so any valid evcn is
bounded by the volume's total cluster count, which ntfs3 holds in
sbi->used.bitmap.nbits (set up in ntfs_init_from_boot() before any caller
of mi_enum_attr() runs). Reject evcn values that fall outside this range.
However, an empty non-resident attribute (no allocated clusters) is
legitimately encoded with svcn == 0 and evcn == -1 (U64_MAX), e.g. via
attr->nres.evcn = cpu_to_le64((u64)vcn - 1) with vcn == 0. That sentinel
must keep passing, so exclude evcn == U64_MAX from the range check. The
existing "svcn > evcn + 1" test still tolerates the sentinel ("0 > 0" is
false) and continues to require svcn == 0 for it, while the range check
rejects every other out-of-range evcn and thereby also defuses the
"evcn + 1" wraparound.
svcn does not need its own bound: once evcn < nbits, "svcn > evcn + 1"
implies svcn <= nbits.
[almaz.alexandrovich@paragon-software.com: fixed evcn check] |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix NULL pointer dereference in nvmet_execute_identify_ns_zns()
When a host issues an Identify command with CNS 05h (I/O Command Set
specific Identify Namespace) and CSI 02h (ZNS) targeting a file-backed
namespace, nvmet_execute_identify_ns_zns() calls bdev_is_zoned() on
req->ns->bdev. A file-backed namespace has no block device, so
req->ns->bdev is NULL and bdev_is_zoned() dereferences it, oopsing.
The I/O command set is selected by the host-supplied CSI field and the
command is routed here whenever CONFIG_BLK_DEV_ZONED is enabled,
independent of the namespace backing type, so any file-backed namespace
is exposed.
Reject the command with Invalid Field when the namespace is not backed
by a block device. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: dwc: ep: Flush cached MSI write before unmapping the iATU
The MSI-X path already flushes any posted MSI-X write before tearing down
its iATU mapping. That was added by commit c22533c66cca ("PCI: dwc: ep:
Flush MSI-X write before unmapping its ATU entry") to make sure the write
reaches the Root Complex before the outbound window that translates it
disappears.
The MSI path has the same problem but no equivalent flush. When the
Endpoint driver caches an MSI target address and later observes that the
Root Complex has changed it, dw_pcie_ep_raise_msi_irq() unmaps the existing
iATU entry and reprograms it for the new address. Between the last MSI
writel() and the unmap there may still be a posted write sitting in the
fabric, and unmapping the iATU entry can drop or misroute that write.
Fix this by reading back from the mapped MSI window before the unmap. The
readback drains any posted MSI writes through the same iATU entry that
mapped them, which is the same logic the MSI-X path uses.

| In the Linux kernel, the following vulnerability has been resolved:
swiotlb: Preserve allocation virtual address for dynamic pools
swiotlb_alloc_tlb() can allocate from the DMA atomic pool when a decrypted
pool is needed from atomic context. With CONFIG_DMA_DIRECT_REMAP, the
atomic pool is backed by remapped virtual addresses, which are not the same
as the direct-map addresses returned by phys_to_virt().
swiotlb_init_io_tlb_pool() currently reconstructs the pool virtual address
from the physical start address. For atomic-pool backed allocations this
stores the wrong address in pool->vaddr. Later, swiotlb_free_tlb() passes
that address to dma_free_from_pool(), which will fail to recognize the
chunk
Pass the virtual address returned by the allocation path into
swiotlb_init_io_tlb_pool(), and store that address in pool->vaddr. This
keeps the pool free path using the same virtual address as the allocator. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Require exactly one Stream ID for a vSID
tegra241_vintf_init_vsid() maps a guest vSID to a single physical Stream ID
taken from master->streams[0], and only warns when the device does not have
exactly one stream. A device with several streams gets only its first one
mapped, so a guest vSID invalidation cannot reach the others' ATC and IOTLB
entries; a device with none makes master->streams a ZERO_SIZE_PTR, read out
of bounds.
Reject the mapping with -EOPNOTSUPP if master->num_streams is not one. |
| In the Linux kernel, the following vulnerability has been resolved:
uio: Fix stale info pointer in failed registration path
After device_add(), the UIO device is visible to userspace and /dev/uioX
can be opened. If a later setup step fails, __uio_register_device()
unwinds the device but leaves idev->info pointing at the caller-owned
struct uio_info.
That is unsafe when an opener races with the failed registration path.
The open file keeps a reference to the uio_device, while the caller sees
registration failure and may free its struct uio_info. Later file
operations can then follow idev->info and dereference freed memory.
Handle post-device_add() failures like unregister: remove UIO attributes
while the info pointer is still valid, then clear idev->info under
info_lock and wake existing waiters/async users before removing the
device and minor. This makes already-open file descriptors observe the
same "device gone" state as normal uio_unregister_device(). |

| The WP Photo Album Plus plugin for WordPress is vulnerable to Remote Code Execution in all versions via the wppa_image_magick function. This is due to insufficient sanitization of the multipart upload filename before concatenation into an ImageMagick command string executed via exec(), with only escapeshellcmd() applied to the whole command rather than quoting individual arguments. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. escapeshellcmd() escapes shell metacharacters but does not prevent argument injection because spaces remain as argument separators, and the filename sanitization applied at the database layer is never applied to the physical temporary file path used for ImageMagick processing. |
| In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check block offset is not negative
If a negative offset is read off disk (for example the offset into the
decompressed fragment block), this will cause squashfs_copy_data() to
perform an out of bounds access.
Fix by checking if offset is negative, and returning 0. This matches
existing behaviour where an offset beyond the block returns 0 bytes
copied.
To trigger this out of bounds access requires a crafted Squashfs
filesystem and CAP_SYS_ADMIN to mount it. Unprivileged users will not be
able to mount such a filesystem, but once mounted, an unprivileged user
can trigger the out of bounds access by reading the crafted file with the
negative offset. |

ALSA: seq: midi: Serialize input teardown with event_input
snd_midi_input_event() must not be running while a rawmidi substream is
closing, since this can lead to the trigger state becoming out-of-step
through this sequence in snd_rawmidi_input_trigger():
snd_rawmidi_input_trigger(up=0)
snd_midi_input_event()
-> snd_rawmidi_kernel_read()
-> snd_rawmidi_input_trigger(up=1)
-> cancel_work_sync()
which ends with the underlying device being active unexpectedly.
When this is called from close_substream(), further input can re-trigger
the input event leaving it running after rawmidi_release_priv() has set
rfile->rmidi to NULL which leads to:
Unable to handle kernel NULL pointer dereference at virtual address 00000000000000b0

Apply a similar approach to commit ef7607ab1c8ad ("ALSA: seq: midi:

proposed follow-on patch [1].
With this change in place, midisynth_unsubscribe() clears the input file
so snd_midi_input_event() will not re-trigger the stream and will be
quiesced by the cancel_work_sync() in snd_rawmidi_input_trigger().

nfc: llcp: read llcp_sock->local under the socket lock in getsockopt
nfc_llcp_getsockopt() read llcp_sock->local before lock_sock(sk) and
then dereferenced the cached pointer inside the locked region.
llcp_sock_bind() assigns and clears llcp_sock->local under the same

Move the llcp_sock->local read and the NULL check inside the
lock_sock(sk) region so bind() cannot mutate or free the pointer between
the load and the use. |
