CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
media: video-i2c: use vb2_video_unregister_device on driver removal
The driver uses vb2_fop_release() as its file release operation, so
vb2_video_unregister_device() should be used instead of
video_unregister_device() during driver removal.
This ensures that the vb2 queue is properly disconnected before the
video device is unregistered. |
| In the Linux kernel, the following vulnerability has been resolved:
ovl: fix UAF in ovl_do_mkdir() debug print
ovl_do_mkdir() prints the input dentry with %pd after vfs_mkdir().
Since commit fe497f0759e0 ("VFS: change vfs_mkdir() to unlock on
failure."), vfs_mkdir() calls end_creating() on the input dentry on
failure and may replace it on success, so the post-call %pd can
use-after-free the dentry when CONFIG_OVERLAY_FS_DEBUG is enabled.
Print the dentry before the call and only the result afterward. |
| In the Linux kernel, the following vulnerability has been resolved:
rtc: dev: zero-initialize struct rtc_wkalrm to prevent information leak
The struct rtc_wkalrm has padding holes after the 'pending' member.
When returned to userspace via the RTC_WKALRM_RD ioctl, uninitialized
kernel stack data residing in these holes may be leaked.
Zero-initialize the struct at declaration to eliminate this information
leak risk.
Fixes smatch warnings:
- drivers/rtc/dev.c:392 rtc_dev_ioctl() warn: check that 'alarm' doesn't
leak information (struct has a hole after 'pending') |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: reset ar->num_stations on hardware start
When (multiple) hw restart occurs, we end up in a situation where we
cannot accept new stations / mesh peers. This seems to be the
'num_stations' in 'struct ath11k' that did not get reset properly in
this case. In ath11k_mac_op_start(), it was indeed the only accounting var
that did not get reset so let's clear it too.
This avoids problems like those:
