CVE-2024-53108
📋 TL;DR
This CVE describes an out-of-bounds read vulnerability in the AMD display driver within the Linux kernel. The vulnerability occurs when parsing EDID data for replay feature support, potentially allowing attackers to read kernel memory. This affects Linux systems with AMD graphics hardware using the affected kernel versions.
💻 Affected Systems
- Linux kernel with AMD display driver (drm/amd/display)

Worst Case
Kernel memory disclosure leading to information leakage, potential privilege escalation if combined with other vulnerabilities, or system crash/instability.
Likely Case
Information disclosure of kernel memory contents, potentially exposing sensitive data or causing system instability.
If Mitigated
Minimal impact with proper kernel hardening, KASAN detection, and memory protection mechanisms in place.
🎯 Exploit Status
Exploitation requires local access and ability to influence EDID data or trigger the vulnerable code path. The vulnerability is an out-of-bounds read, not a write, limiting direct exploitation potential.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Kernel versions containing commits: 0a326fbc8f72a320051f27328d4d4e7abdfe68d7, 16dd2825c23530f2259fc671960a3a65d2af69bd, 8db867061f4c76505ad62422b65d666b45289217
Vendor Advisory: https://git.kernel.org/stable/c/0a326fbc8f72a320051f27328d4d4e7abdfe68d7
Restart Required: Yes
Instructions:
1. Update Linux kernel to a version containing the fix commits. 2. For distributions: Use package manager (apt, yum, dnf) to update kernel. 3. Reboot system to load new kernel.
