CVE-2024-53108: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-53108 affects the Linux kernel's AMD display driver, specifically related to the VSDB parser for replay feature. The vulnerability was discovered when the IEEE ID identification for the replay check in the AMD EDID was added, causing out-of-bounds issues when using KASAN. The issue was disclosed on December 2, 2024, and affects Linux kernel versions up to 6.6.63 and from 6.7 to 6.11.10 (NVD).

The vulnerability is classified as an out-of-bounds read (CWE-125) with a CVSS v3.1 base score of 7.1 (HIGH). The issue occurs because the ID extraction happens outside the range of the EDID length in the AMD display driver. When using KASAN, it triggers a slab-out-of-bounds error in the amdgpu_dm_update_freesync_caps function, attempting to read memory at an invalid address (Kernel Patch).

The vulnerability could lead to information disclosure or system crashes due to the out-of-bounds read in the AMD display driver. The high CVSS score indicates significant potential impact, particularly affecting system confidentiality and availability (NVD).

The issue has been patched by adjusting the VSDB parser to consider the amd_vsdb_block size when processing EDID data. The fix involves modifying the while loop condition to prevent reading beyond the buffer's bounds. Users should update their Linux kernel to versions that include the fix (Kernel Patch).
