In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix use-after-free in llcp_sock_release() llcp_sock_release()… (CVE-2026-64011)
In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix use-after-free in llcp_sock_release() llcp_sock_release() unconditionally unlinks the socket from the local sockets list. However, if the socket is still in connecting state, it is on the connecting list. Fix this by checking the socket state and unlinking from the correct list.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel NFC component involves the llcp_sock_release() function unconditionally unlinking a socket from the local sockets list without checking if the socket is in a connecting state. If the socket is still connecting, it resides on a different list (the connecting list), causing a use-after-free condition when the unlink operation is performed incorrectly. The fix involves verifying the socket state and unlinking it from the appropriate list to prevent this memory corruption issue.
Potential Impact
This vulnerability could lead to use-after-free memory corruption within the kernel NFC subsystem, potentially causing system instability or crashes. No specific exploit or widespread attacks are known at this time.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should apply the official kernel updates that include this patch. Since no patch links or vendor advisories are provided here, check the official Linux kernel repositories or vendor advisories for the relevant fixed kernel versions and update accordingly.
