CVE-2023-52502

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a race condition in the NFC component of the Linux kernel, specifically in the nfc llcp sock get() and nfc llcp sock get sn() functions. This can lead to a Use After Free (UAF) condition, potentially allowing an attacker to execute arbitrary code with elevated privileges. The problem occurs when getting a reference on the socket found in a lookup while holding a lock, which should happen before releasing the lock. The nfc llcp recv snl() function also needs to ensure that the socket found by nfc llcp sock from sn() does not disappear.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
