Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fixed integer overflow in amdgpucspass1. The type of size is unsigned int. If size is 0x40000000, there will be an integer overflow. After size = sizeofuint32t, size will become zero, which may lead to referencing...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Install a stub fence into potential unused fence pointers. When using cpu to update page tables, VM update fences are unused. Install a stub fence into these fence pointers instead of using NULL. This prevents NULL...
