CVE-2024-56554

7.8 · HIGH
Published Dec 27, 2024 linux CWE-416 EPSS 0.21% (12th pctl)

Overview

CVE-2024-56554 is a high-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

binder: fix freeze UAF in binder_release_work()

When a binder reference is cleaned up, any freeze work queued in the

associated process should also be removed. Otherwise, the reference is

freed while its ref->freeze.work is still queued in proc->work leading

to a use-after-free issue as shown by the following KASAN report:
