Linux Kernel, Memory Corruption Vulnerability, CVE-2024-50187 (Moderate)
This article describes a vulnerability (CVE-2024-50187) in the Linux kernel’s drm/vc4 driver. The issue arises when closing a file descriptor with an active performance monitor. While the monitor itself is destroyed, a pointer to it remains. If a new file descriptor is opened and uses performance monitors, the driver attempts to stop the old (non-existent) monitor using this stale pointer, leading to potential memory corruption.
Here’s the summarized information:
Platform: Linux Kernel
Version: Not specified (all versions potentially affected)
Vulnerability: Memory Corruption in drm/vc4 driver
Severity: Moderate (CVSS v3 score to be determined)
Date: November 8, 2024 (CVE published)
