Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 6.11.2. This affects an unknown part of the component AMD Display. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null pointers before multiple uses [WHAT & HOW] Poniters, such as stream_enc and dc->bw_vbios, are null checked previously in the same function, so Coverity warns "implies that stream_enc and dc->bw_vbios might be null". They are used multiple times in the subsequent code and need to be checked. This fixes 10 FORWARD_NULL issues reported by Coverity.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2024-49920 since 10/21/2024. The technical details are unknown and an exploit is not publicly available.
