In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix a null pointer access when the smc_rreg pointer is NULL

The Linux kernel CVE team has assigned CVE-2023-52817 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024052104-CVE-2023-52817-ba29@gregkh/T

Comment 4 Alex 2024-06-09 16:10:31 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52817 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is an approximation based on flags DANGER NULLPTR  ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
