CVE-2024-14027
5.5 · MEDIUMOverview
CVE-2024-14027 is a medium-severity vulnerability affecting linux linux_kernel. It was published on March 9, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
fs/xattr: missing fdput() in fremovexattr error path
In the Linux kernel, the fremovexattr() syscall calls fdget() to acquire a
file reference but returns early without calling fdput() when
strncpy_from_user() fails on the name argument. In multi-threaded processes
where fdget() takes the slow path, this permanently leaks one
file reference per call, pinning the struct file and associated kernel
objects in memory. An unprivileged local user can exploit this to cause
kernel memory exhaustion. The issue was inadvertently fixed by commit
a71874379ec8 ("xattr: switch to CLASS(fd)").
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
