Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to v5.10.121
Description
The issue is related to a potential security vulnerability in the NFC component, where the dev->rfkill is not properly NULLed out, which could lead to a use-after-free (UAF) condition. The actual impact and attack plausibility have not yet been proven.
Recommendations
For Linux Kernel versions prior to v5.10.121, update to version v5.10.121 or later to resolve the issue. As a temporary workaround, consider implementing custom memory management to prevent UAF conditions until a patch is available.
