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 in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed the amdgpuirqput call trace in gmcv110hwfini The gmc.eccirq is enabled by the firmware based on the IFWI setting. The host driver does not have privileges to enable/disable the interrupt. Therefore, using the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: Do not allow userspace to trivially trigger kernel warnings. Userspace can either deliberately pass in a too-small numfences value, or the required number can legitimately increase between the two calls to the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: A memory leak has been fixed in hpdrxirqcreateworkqueue. If the construction of the array of work queues to handle hpdrxirq offload fails, we need to unwind the process. All created workqueues and the allocated memory...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Added a upper bound check on user inputs in wait ioctl. Large input values in amdgpuuserqwaitioctl can lead to a Out-of-Memory OOM condition, and this vulnerability could be exploited. Therefore, it is recommended to...
