Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: amdgpu/pm: prevented array underflow in vega20odneditdpmtable In the PPODEDITVDDCCURVE case, the “inputindex” variable is capped at 2, but its negative values are not checked, resulting in an out-of-bounds read. This value comes...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: Fixed a reference leak in amdgpuuserqwaitioctl. Also, removed the reference to syncobj and timeline fence when aborting the ioctl, as the output array became too small. Selected from the commit...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed an access race in the gpu recovery process. A potential UAF Uninitialized Address Fault during GPU recovery was avoided due to a race between the sched timeout callback and the tdr work queue. The gpu recovery...
