VetorAV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.3.8
Description The issue is related to a memory leak in the clock source create() function under /gpu/drm/amd/display/dc in the Linux kernel. This leak can be exploited by a remote attacker to cause a denial of service due to memory consumption. The affected functions include dce112 clock source create(), dce100 clock source create(), dcn10 clock source create(), dcn20 clock source create(), dce120 clock source create(), dce110 clock source create(), and dce80 clock source create().
Recommendations For Linux kernel versions prior to 5.3.8, update to version 5.3.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the affected functions until a patch is applied.
