CVE-2024-46725: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-46725 is a vulnerability discovered in the Linux kernel affecting the AMD GPU driver (drm/amdgpu). The issue was identified as an out-of-bounds write warning in the ring type value handling. The vulnerability was disclosed on September 18, 2024, and affects multiple versions of the Linux kernel up to versions 5.10.226, 5.15.167, 6.1.109, 6.6.50, and 6.10.9 (NVD).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) issue in the AMD GPU driver's ring initialization function. The problem occurs in the amdgpu_ring.c file where there was insufficient validation of the ring type value before accessing the GPU scheduler array. The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local access requirements but high potential impact (NVD).

The vulnerability could potentially lead to out-of-bounds write operations in the kernel's memory space, which could result in system crashes, memory corruption, or potential privilege escalation. Given the CVSS score of 7.8, the vulnerability has high potential impact on the confidentiality, integrity, and availability of the affected system (NVD).

The vulnerability has been patched in the Linux kernel by adding additional validation checks for the ring type value. The fix involves checking if the ring type is less than AMDGPUHWIP_NUM before accessing the GPU scheduler array. The patch has been applied to multiple kernel versions and is available through various distribution updates (Kernel Patch).
