CVE-2024-49922

The CVE-2024-49922 entry concerns the Linux kernel DRM AMD display driver. The issue arises from using pointers that may be NULL in a path where they had been validated earlier in the same function, triggering null-pointer handling after use. The vulnerability is mitigated by a fix that adds null...

CVE-2024-49920 drm/amd/display: Check null pointers before multiple uses

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null pointers before multiple uses WHAT & HOW Poniters, such as streamenc and dc-bwvbios, are null checked previously in the same function, so Coverity warns "implies that streamenc and dc-bwvbios might be...

CVE-2024-49920

The CVE-2024-49920 entry concerns the Linux kernel DRM/AMD display subsystem. The vulnerability arises from a null-pointer risk in the AMD display path, where pointers such as stream_enc and dc->bw_vbios are used multiple times after a check that is only performed earlier in the function. The ...
