CVE-2024-53050: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-53050 is a vulnerability in the Linux kernel affecting the HDCP (High-bandwidth Digital Content Protection) capability check functionality. The issue was discovered in the drm/i915/hdcp component, specifically in the hdcp2getcapability function, where a missing encoder check could lead to a null pointer error. The vulnerability affects Linux kernel versions up to (excluding) 6.11.7 (NVD).

The vulnerability is classified as a NULL Pointer Dereference (CWE-476) with a CVSS v3.1 base score of 5.5 (Medium). The issue occurs in the intelhdcp2getcapability function where the code failed to properly validate the encoder before accessing it. The vulnerability requires local access and low privileges to exploit. The technical fix involves adding an encoder check in the hdcp2get_capability function to prevent the null pointer error (Kernel Patch).

The vulnerability could lead to a system crash or denial of service condition when the HDCP capability check is performed on affected systems. The impact is limited to availability (A:H in CVSS score) with no direct effects on confidentiality or integrity (NVD).

The vulnerability has been fixed in Linux kernel version 6.11.7 and later. Users should update their kernel to a patched version. The fix involves adding proper encoder validation checks in the intelhdcp2get_capability function (Kernel Patch).
