CVE-2024-41076

A vulnerability was found in the nfs4_set_security_label() in the Linux kernel, where the function fails to free the nfs_fattr attribute before exiting, leaving said memory allocation present. As the nfs4_set_security_label() is called repeatedly over time, this may lead to memory exhaustion.

Red Hat believes this flaw to be of low severity as the only effect of this vulnerability is to lead to memory leakage which, called repeatedly over time, may lead to memory exhaustion and impact the system's performance. Given that the max xattr size on NFSv4 systems is quite small (typically 1KB; and security xattrs tend to be significantly smaller) it is safe to assume that a system's availability being impacted solely from memory exhaustion caused by this vulnerability is unlikely and thus its impact is low.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

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.
