NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel6.12-libbpf-debuginfo package and not the kernel6.12-libbpf-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

media: videobuf2: forbid remove_bufs when legacy fileio is active

vb2_ioctl_remove_bufs() call manipulates queue internal buffer list, potentially overwriting some pointers used by the legacy fileio access mode. Forbid that ioctl when fileio is active to protect internal queue state between subsequent read/write calls.
