CVE-2024-26699: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-26699 affects the Linux kernel's AMD display driver (drm/amd/display), specifically in the dcn35_clkmgr component. The vulnerability was discovered and disclosed on April 3, 2024. The issue involves a potential memory access violation while iterating through an array of dcn35 clocks, affecting Linux kernel versions up to 6.7.6 (NVD).

The vulnerability is an array-index-out-of-bounds issue in the dcn35_clkmgr component of the AMD display driver. The problem occurs due to improper validation of array indices when iterating through clock arrays. 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. The issue is classified as CWE-129 (Improper Validation of Array Index) (NVD).

The vulnerability could lead to memory access violations when accessing the dcn35 clocks array. This could potentially result in system crashes, information disclosure, or privilege escalation in the context of the kernel. The high CVSS score indicates significant potential impact on system confidentiality, integrity, and availability (NVD).

The vulnerability requires local access and low privileges to exploit. The attack complexity is low, and no user interaction is required. The vulnerability affects Linux kernel versions prior to 6.7.7 and various distribution-specific kernel versions (NVD).

The vulnerability has been fixed by limiting iteration per array size in the affected component. The fix was implemented in Linux kernel version 6.7.7 and backported to supported stable kernel versions. The patch involves adding proper bounds checking for array iterations in the dcn35_clkmgr component (Kernel Patch).
