CVE-2024-53165
Description
A flaw was found in the Linux kernel's sh: intc component. Incorrect error handling within the register_intc_controller() function can lead to a use-after-free vulnerability. This occurs when a data structure is freed but not removed from an internal list, allowing subsequent operations to access freed memory. A local attacker could potentially exploit this to achieve privilege escalation, arbitrary code execution, or cause a denial of service.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
