PT-2024-35572
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.65 Description The issue is caused by the ID extraction happening outside of the range of the edid length in the AMD EDID, leading to out-of-bounds issues when using KASAN. This results in a slab-out-of-bound...

Linux kernel dmub_callback dmub_thread_offload Use-After-Free
The vulnerability of the dmubcallback and dmubthreadoffload functions defined in the drivers/gpu/drm/amd/display/amdgpudm/amdgpudm.h header of the Linux kernel’s CPU is related to insufficient memory allocation, which leads to memory reading beyond the allocated buffer. Exploiting this...
amdgpu link_destruct() Data Compromise
The vulnerability of the linkdestruct function in the drivers/gpu/drm/amd/display/dc/link/linkfactory.c file of the amdgpu kernel in the Linux operating system is related to the re-release of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the...
