CVE-2024-46718
CVE-2024-46718 is a vulnerability in the Linux kernel's drm/xe component related to identity VRAM mapping. This issue involves the kernel potentially overmapping the identity VRAM mapping, which can trigger hardware bugs on specific platforms. The fix involves utilizing 2MB pages for the last VRAM chunk that is unaligned to 1GB to prevent the overmapping problem. Despite a CVSS score of 0, indicating a seemingly low immediate impact, the SOCRadar Vulnerability Risk Score (SVRS) of 30 suggests a moderate risk, potentially escalating with further exploit development or specific system configurations. This kernel flaw requires patching to ensure system stability and prevent potential hardware-related issues. Ignoring this vulnerability could lead to unpredictable system behavior or crashes on affected systems. Keeping your Linux kernel updated is important to mitigate this and other potential security risks.
Description:
CVE-2024-46718 is a vulnerability in the Linux kernel that could allow an attacker to trigger hardware bugs on certain platforms by overmapping the identity VRAM mapping. This vulnerability has a CVSS score of 0, indicating a low severity level. However, SOCRadar's unique 'SOCRadar Vulnerability Risk Score' (SVRS) assigns a score of 34, indicating a moderate risk level. This discrepancy highlights the importance of considering additional factors beyond CVSS when assessing the severity of vulnerabilities.
