Описание
In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has a fence use-after-free.
A use-after-free flaw was found in the Linux kernel's AMD GPU driver which may allow access to members of a synchronization structure after the structure is freed. This issue could allow a local user to crash the system or to access confidential system memory.
Отчет
This issue is only applicable to the amdgpu module, which is typically only loaded on systems that use AMD GPU hardware. Use the lsmod command to determine whether the amdgpu module is loaded.
Меры по смягчению последствий
To mitigate this issue, prevent the amdgpu module from loading. Please see https://access.redhat.com/solutions/41278 for more information on how to prevent kernel modules from loading. Note that if a system has an AMD GPU, this may make certain features of that GPU unavailable.
