Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed a DRM panic due to a null pointer when the driver does not support atomic operations. When the driver does not support atomic operations, fb uses plane-fb instead of plane-state-fb. Cherry-picked from commit...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/fence: Fixed an oops due to incorrect drmsched init/fini calls. Currently, amdgpu calls drmschedfini from the fence driver’s fini routine. Such a call is expected to occur only after the respective init function,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/pm: fixed the null pointer issue when the SMU is disabled. It is necessary to check whether the ppfuncs is initialized before releasing the context; otherwise, a null pointer panic will occur when the software SMU is n...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Null checks for adev-dm.dc in amdgpudmfini have been fixed. Since adev-dm.dc in amdgpudmfini might turn out to be NULL before the call to dcenabledmubnotifications, a check is performed beforehand to ensure that...
