CVE-2024-57982
Description
A flaw was found in the Linux kernel. This vulnerability allows a local user to cause a Denial of Service (DoS) via a system crash. A race condition between table resizing and state lookup operations in the IPsec packet transformation (xfrm) subsystem can cause the kernel to perform an out-of-bounds memory read during concurrent state lookups.
Statement
This vulnerability is rated as Moderate impact because exploiting the race condition requires precise timing during IPsec state table resizing, with the primary blast radius limited to a denial of service via a kernel crash rather than arbitrary code execution. In Red Hat Enterprise Linux environments, the xfrm framework is utilized when IPsec packet transformation or tunneling services are active, and modifying state tables generally requires administrative networking privileges. Systems that do not actively manage or process IPsec traffic are unlikely to encounter the concurrent table modification conditions necessary to trigger this flaw.
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).
