About this tag
CVE-2026-23372 is a Linux kernel vulnerability in the NFC rawsock subsystem that involves a workqueue race condition leading to a use-after-free (UAF) risk. The bug occurs when transmit work outlives socket teardown, potentially causing instability or privilege boundary issues. The fix addresses the race by properly synchronizing workqueue activity with device lifetimes and asynchronous cleanup. Administrators should apply the kernel patch to mitigate the risk of system compromise or data corruption.
