Detailsinfo

A vulnerability was found in Linux Kernel up to 5.15.151/6.1.81/6.6.17/6.7.5. It has been classified as critical. This affects an unknown code block of the component amdgpu. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Reset IH OVERFLOW_CLEAR bit Allows us to detect subsequent IH ring buffer overflows as well.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2024-26915 since 02/19/2024. The exploitability is told to be easy. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/13/2024).
