Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Stop amdgpu_dm initialize when link nums greater than max_links
[Why]
Coverity report OVERRUN warning. There are
only max_links elements within dc->links. link
count could up to AMDGPU_DM_MAX_DISPLAY_INDEX 31.
[How]
Make sure link count less than max_links.
A flaw was found in the Linux kernel's amdgpu_dm display driver. This vulnerability occurs when the driver attempts to initialize more display links than its allocated memory can accommodate, leading to a buffer overrun. A local attacker could exploit this issue to cause a system crash, resulting in a denial of service.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
