CVE-2024-35882
Description
A memory leak vulnerability was found in the Linux kernel's SUNRPC implementation for RPC-over-TCP. The issue occurs because the sock_sendmsg() function does not release all memory pages in the underlying bio_vec array, causing a slow memory leak that affects servers using NFS and can lead to memory exhaustion over time.
Statement
Red Hat Enterprise Linux is not vulnerable to this CVE, as it does not affect the versions or configurations of the Linux kernel used in its distributions.
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.
