Описание
In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race condition between a nonblocking atomic commit and a driver unload.
A flaw was found in the Linux kernel Direct Rendering Infrastructure (DRI) subsystem in which a use-after-free can be caused when a user triggers a race condition between a nonblocking atomic commit and a driver unload. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
Отчет
The Red Hat Enterprise Linux 8 and Red Hat Enterprise Linux 9 affected. The impact level is Moderate, because potential use-after-free could happen only during loading/unloading driver (that requires some privileges).
Меры по смягчению последствий
To mitigate this issue, prevent module drm from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
