A flaw was found in the Linux kernel’s Near Field Communication (NFC) subsystem. The issue involves a use-after-free condition introduced by commits to fix reference count leaks. This vulnerability can be triggered if the same local address is assigned to two different sockets, leading to a potential system crash or other unpredictable behavior.
