Description
A flaw was found in the Near Field Communication (NFC) Logical Link Control Protocol (LLCP) subsystem of the Linux kernel. A race condition exists between the nfc_llcp_getsockopt() and llcp_sock_bind() functions. This allows a local attacker to potentially cause a use-after-free vulnerability by racing a getsockopt() call with an in-flight bind() operation, leading to memory corruption or a denial of service.
