CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Correctly handle return of sg_nents_for_len
The return value of sg_nents_for_len was assigned to an unsigned long
in starfive_hash_digest, causing negative error codes to be converted
to large positive integers.
Add error checking for sg_nents_for_len and return immediately on
failure to prevent potential buffer overflows. |
| Insufficient control flow management in the Linux kernel-mode driver for some Intel(R) 800 Series Ethernet before version 1.17.2 may allow an authenticated user to potentially enable escalation of privilege via local access. |
| In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()
In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the
subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function
returns an error without freeing sskb, leading to a memory leak.
Fix this by calling dev_kfree_skb() on sskb in the error handling path
to ensure it is properly released. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/sysfb: Do not dereference NULL pointer in plane reset
The plane state in __drm_gem_reset_shadow_plane() can be NULL. Do not
deref that pointer, but forward NULL to the other plane-reset helpers.
Clears plane->state to NULL.
v2:
- fix typo in commit description (Javier) |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()
If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success. |

to track the number of threads which calling f2fs_write_cache_pages().
- use .i_sem lock to protect .writeback update.
- check .writeback before update compression context in f2fs_setflags_common()
to avoid race w/ ->writepages. |
| In the Linux kernel, the following vulnerability has been resolved:
ns: initialize ns_list_node for initial namespaces
Make sure that the list is always initialized for initial namespaces. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: rng - Ensure set_ent is always present
Ensure that set_ent is always set since only drbg provides it. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: ti_am335x_tsc - fix off-by-one error in wire_order validation
The current validation 'wire_order[i] > ARRAY_SIZE(config_pins)' allows
wire_order[i] to equal ARRAY_SIZE(config_pins), which causes out-of-bounds
access when used as index in 'config_pins[wire_order[i]]'.
Since config_pins has 4 elements (indices 0-3), the valid range for
wire_order should be 0-3. Fix the off-by-one error by using >= instead
of > in the validation check. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't log conflicting inode if it's a dir moved in the current transaction
We can't log a conflicting inode if it's a directory and it was moved
from one parent directory to another parent directory in the current
transaction, as this can result an attempt to have a directory with
two hard links during log replay, one for the old parent directory and
another for the new parent directory.
The following scenario triggers that issue:
1) We have directories "dir1" and "dir2" created in a past transaction.
Directory "dir1" has inode A as its parent directory;
2) We move "dir1" to some other directory;
3) We create a file with the name "dir1" in directory inode A;
4) We fsync the new file. This results in logging the inode of the new file
and the inode for the directory "dir1" that was previously moved in the
current transaction. So the log tree has the INODE_REF item for the
new location of "dir1";
5) We move the new file to some other directory. This results in updating
the log tree to included the new INODE_REF for the new location of the
file and removes the INODE_REF for the old location. This happens
during the rename when we call btrfs_log_new_name();
6) We fsync the file, and that persists the log tree changes done in the
previous step (btrfs_log_new_name() only updates the log tree in
memory);
7) We have a power failure;
8) Next time the fs is mounted, log replay happens and when processing
the inode for directory "dir1" we find a new INODE_REF and add that
link, but we don't remove the old link of the inode since we have
not logged the old parent directory of the directory inode "dir1".
As a result after log replay finishes when we trigger writeback of the
subvolume tree's extent buffers, the tree check will detect that we have
a directory a hard link count of 2 and we get a mount failure.
The errors and stack traces reported in dmesg/syslog are like this:

The issue was reported on 12th of August and was ignored by author of
commits introducing issue for two weeks. Only after complaining author
produced a fix which did not work, so if original commits cannot be
reliably fixed for 5 weeks, they obviously are buggy and need to be
dropped. |

net/mlx5: Fix double unregister of HCA_PORTS component
Clear hca_devcom_comp in device's private data after unregistering it in
LAG teardown. Otherwise a slightly lagging second pass through
mlx5_unload_one() might try to unregister it again and trip over
use-after-free.
On s390 almost all PCI level recovery events trigger two passes through
mxl5_unload_one() - one through the poll_health() method and one through
mlx5_pci_err_detected() as callback from generic PCI error recovery.
While testing PCI error recovery paths with more kernel debug features
enabled, this issue reproducibly led to kernel panics with the following
call chain:
