CVSS v3.1 |
| IBM Guardium Data Protection 12.2 could allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss
If a peer's VHT/HE MCS map has no supported spatial stream (all fields
0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),
which was then written into the firmware sta_rec_bf beamforming fields.
Clamp the result to 0. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix vmlinux BTF prep race in bpf_get_btf_vmlinux
bpf_get_btf_vmlinux() lazily parses the vmlinux BTF under the
bpf_verifier_lock, but publishes the result through a plain store
and re-checks it through a plain lockless load. Nothing orders
the stores initializing the struct btf inside btf_parse_vmlinux()
against the store publishing the pointer: On a weakly ordered
arch, a concurrent first-time caller taking the lockless fast
path could in principle observe the pointer before the parsed
contents are visible. The mutex_unlock() does not help such a
reader given it only synchronizes with a later acquisition of the
same lock. Thus, publish the pointer with smp_store_release()
and read it on the fast path with smp_load_acquire().
Acquire semantics are needed rather than a dependency-ordered
READ_ONCE(): btf_parse_vmlinux() also populates globals outside
the returned object (e.g. bpf_ctx_convert.t). An address
dependency would only order accesses performed through the
pointer and not cover other globals. |
| The Booking Calendar plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 11.8.2 via the `wpbc_ajax_option_save` AJAX action. The vulnerability exists because the `handle_ajax_save()` function applies per-option safeguards only to names explicitly registered via `register_option_policy()`, causing `get_option_policy()` to return an empty policy — bypassing all can_save, force_mode, and allowed_keys checks — for any unregistered option name, including core WordPress options, while an attacker-controlled `data_name` parameter passes through `sanitize_key()` and is written directly to `update_option()` without restriction. This makes it possible for authenticated attackers with Editor-level access and above to escalate their privileges to Administrator by writing core WordPress options such as `default_role=administrator` and `users_can_register=1`, then self-registering a new Administrator account. The nonce check does not meaningfully restrict this attack, as both the nonce value and nonce action are attacker-supplied POST parameters, and a valid nonce is trivially obtainable via `admin-ajax.php?action=rest-nonce`. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Add refcounting to user ring MRs
Prevent userspace from deregistering the MRs that back QP/CQ/SRQ rings
by bumping the MR's refcount upon association. |
| go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: xilinx_dma: Fix channel idle state management in AXIDMA and MCDMA interrupt handlers
Fix a race condition in AXIDMA and MCDMA irq handlers where the channel
could be incorrectly marked as idle and attempt spurious transfers when
descriptors are still being processed.
The issue occurs when:
1. Multiple descriptors are queued and active.
2. An interrupt fires after completing some descriptors.
3. xilinx_dma_complete_descriptor() moves completed descriptors to
done_list.
4. Channel is marked idle and start_transfer() is called even though
active_list still contains unprocessed descriptors.
5. This leads to premature transfer attempts and potential descriptor
corruption or missed completions.
Only mark the channel as idle and start new transfers when the active list
is actually empty, ensuring proper channel state management and avoiding
spurious transfer attempts. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Avoid reprocessing the current packet after the QP enters the error state
When do_complete() finds the QP in the error state it returns
RESPST_CHK_RESOURCE. Before commit 49dc9c1f0c7e ("RDMA/rxe: Cleanup
reset state handling in rxe_resp.c") this was the flush loop:
check_resource() had an error-state branch that fetched each remaining
recv WQE and completed it with IB_WC_WR_FLUSH_ERR, without touching
the current packet. That commit removed the error-state branch from
check_resource() (draining is now done at rxe_receiver() entry) but
kept the do_complete() error-state return.
As a result, when a QP moves to the error state while a packet is
being completed - e.g. an rdma_cm disconnect racing with receive
processing - the responder state machine loops back into the request
processing chain with the already-completed packet still in hand:
check_resource() fetches a fresh recv WQE, execute()/send_data_in()
copies the same packet payload again, do_complete() posts another
IB_WC_SUCCESS CQE (qp->resp.status is still 0), and control returns
to the error-state check. The loop re-executes the same packet once
per posted recv WQE (observed: ~1000 duplicate IB_WC_SUCCESS
completions of one SEND, one per ~8us, matching the RQ occupancy)
until the RQ is exhausted, after which qp->resp.wqe is NULL and
send_data_in() dereferences it:
BUG: kernel NULL pointer dereference, address: 0000000000000014
Workqueue: rxe_wq do_work
RIP: copy_data+0x29/0x1f0
Call Trace:
send_data_in+0x25/0x50
rxe_receiver+0xf36/0x1dd0
The duplicate completions are indistinguishable from real receives to
the ULP. During an rds stress test, the message was accepted as new and
delivered the same datagram to user space hundreds of times, corrupting
the stream; any ULP that relies on RC exactly-once delivery is affected.
A live packet reaching the error-state check in do_complete() has
been executed and completed exactly once and must be consumed, not
re-processed. Return RESPST_CLEANUP for it (dequeue and free); keep
returning RESPST_CHK_RESOURCE for the pkt == NULL case. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject arena frees below the arena base
bpf_arena_free_pages() accepts scalar arena addresses. The runtime
masks the address to the low 32 bits and reconstructs a full user
address from the arena base before returning the range to the arena
free tree.
When the scalar value is below the low 32 bits of the arena base,
full_uaddr falls below user_vm_start. The existing upper-end clipping
then turns this into an out-of-range free-tree offset. A later
allocation can reuse that offset and return an address below the arena
mapping.
Reject such frees before computing the clipped range. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: processor: validate MADT IOAPIC entry bounds
The IOAPIC hotplug lookup parses both MADT and _MAT records directly.
The MADT walk previously used a subtable's declared length to advance
the cursor after only locating a generic header. The _MAT path likewise
passed a generic header to the IOAPIC helper.
Validate that a current record has a complete generic header, that its
declared length is contained in the available record range, and that a
typed IOAPIC record contains the full fixed IOAPIC body before reading
its fields. Use the same relation for both MADT and _MAT provider
paths. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: fix ext PHY use-after-free on register error path
After mt7915_register_ext_phy() succeeded, a failure of the main PHY
mt7915_init_debugfs() or mt7915_coredump_register() unwound through
free_phy2, which called ieee80211_free_hw() on the ext PHY hw while it
was still registered with mac80211, since mt76_unregister_device() only
unregisters the main hw. Unregister the ext PHY (thermal + phy + hw)
first and skip the redundant free. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: unlink TWT flow if the MCU rejects the agreement
The flow is added to dev->twt_list before sending the agreement to the
firmware, but the error path leaves it linked while flowid_mask is
never set. The flow slot can then be reused and memset while still on
the list, corrupting twt_list, and station removal leaves a dangling
entry behind that mt7915_mac_twt_sched_list_add() later walks. |
| In the Linux kernel, the following vulnerability has been resolved:
phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure
for_each_child_of_node_scoped() releases the node reference on scope
exit, so the explicit of_node_put(np) in the devm_phy_create() error
path drops it twice.
Drop the redundant of_node_put() and let the scoped cleanup handle it. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix integer overflow in verify_tags() bounds check
verify_tags() validates the tagset table unpacked from a policy blob.
For each set it reads a count and checks that advancing the index by
that count stays inside sets.table[]:
u32 cnt = tags->sets.table[i];
if (i+cnt >= tags->sets.size) {
i, cnt and sets.size are all u32, so i+cnt is evaluated modulo 2^32.
sets.table[] is filled by unpack_tagsets() with aa_unpack_u32(), so
every entry is a raw unbounded 32-bit word taken from the policy blob,
and verify_tags() is the function that is supposed to validate it. A
count close to U32_MAX makes the sum wrap to a small value, the guard
passes, and the inner loop then walks sets.table[++i] past the end of
the kcalloc(size, sizeof(u32)) allocation.
Note that sets.size is bounded by 65535, because unpack_tagsets() reads
it with aa_unpack_array() as a u16, so the wrap cannot be reached by
growing the table; it is reached purely through the attacker-supplied
count.
With sets.size = 2 and sets.table = { 0, 0xffffffff }:
i = 0: cnt = 0, guard 0 + 0 >= 2 is false, inner loop does not run
i = 1: cnt = 0xffffffff, guard (1 + 0xffffffff) mod 2^32 == 0 >= 2 is
false, so the guard is bypassed and the inner loop reads
sets.table[2] -- one element past a two element allocation
The walk continues until an out-of-bounds value happens to be >=
hdrs.size or the access faults, so a crafted policy yields an
out-of-bounds read on the policy load path
(aa_replace_profiles -> aa_unpack -> unpack_policydb -> unpack_tags ->
verify_tags). unpack_tags() runs before the perms and DFA tables are
unpacked, so no other table needs to be well formed to reach it.
Policy load is gated by aa_may_manage_policy(), which checks
CAP_MAC_ADMIN relative to the subject's own user namespace rather than
the init user namespace, so with the default
unprivileged_userns_apparmor_policy=1 the path is reachable from an
unprivileged task in a matched-level nested namespace, not only by a
globally privileged one.
Perform the addition in u64 so that it cannot wrap, restoring the
intended i + cnt < sets.size guarantee. |
| HUBzero CMS through 2.2.32 contains a path traversal vulnerability in project file upload handlers that allows authenticated project members to write arbitrary files outside the project repository. Attackers can supply traversal sequences in upload parameters to write files to attacker-chosen paths with web server privileges, potentially enabling code execution. |
| Grav is a flat-file CMS. In versions 2.0.0-rc.1 through 2.0.21, the Twig content sandbox fails to restrict the dump and serialize filters (print_r, vardump, json_encode, yaml_encode, string): GravExtension::assertSandboxDumpSafe() determines sandbox state by calling SandboxExtension::isSandboxed() without a Source argument, which reports only the global sandbox flag that Grav never enables, so the guard added in GHSA-mc5q-6hpj-rp7j never executes. As a result, an authenticated user with page-edit rights can render {{ config|print_r }} in page content with Twig processing enabled and dump Grav's entire merged configuration — print_r reflects the real Config object held in a private property of the SandboxConfig facade, bypassing its path redaction — exposing plugin secrets such as SMTP credentials, API tokens, webhook secrets and cache backend passwords. Grav 1.7 is not affected because it ships no Twig content sandbox. The issue is fixed in 2.0.22, where the affected filters are registered with Twig's needs_is_sandboxed flag. |
| Administrator SQL Injection in PublishPress Series <= 3.1.3 versions. |
| Jupyter Server is the backend for Jupyter web applications. Prior to version 2.21.0, the 5xx request logging path in jupyter_server/log.py copies the Referer header into a JSON header block without applying the token scrubbing used for the request URI. A request that returns HTTP 500 while the Referer contains a token-bearing URL can therefore write that token to server logs in plaintext. An attacker who can read those logs can recover the token and use the affected user's Jupyter Server permissions. This issue is fixed in version 2.21.0. |
| OpenNHP through 1.0.2 selects its trusted-execution attestation verifier based on attacker-supplied evidence containing a test_purpose key, causing the FallbackVerifier to execute unconditionally. Attackers can bypass attestation verification by including the test_purpose key in evidence and providing enrolled measure and serial number pairs from the allowlist to gain unauthorized access. |
| Chroma through 1.5.9 fails to validate tenant and database segments when resolving collections, allowing authenticated attackers to access collections from other tenants by knowing the collection identifier. Attackers can read, modify, and update records in foreign collections by issuing requests under their own tenant path, bypassing authorization checks. |
