"value": "In the Linux kernel, the following vulnerability has been resolved:\n\naf_unix: Fix data races in unix_release_sock/unix_stream_sendmsg\n\nA data-race condition has been identified in af_unix. In one data path,\nthe write function unix_release_sock() atomically writes to\nsk->sk_shutdown using WRITE_ONCE. However, on the reader side,\nunix_stream_sendmsg() does not read it atomically. Consequently, this\nissue is causing the following KCSAN splat to occur:\n\n\tBUG: KCSAN: data-race in unix_release_sock / unix_stream_sendmsg\n\n\twrite (marked) to 0xffff88867256ddbb of 1 bytes by task 7270 on cpu 28:\n\tunix_release_sock (net/unix/af_unix.c:640)\n\tunix_release (net/unix/af_unix.c:1050)\n\tsock_close (net/socket.c:659 net/socket.c:1421)\n\t__fput (fs/file_table.c:422)\n\t__fput_sync (fs/file_table.c:508)\n\t__se_sys_close (fs/open.c:1559 fs/open.c:1541)\n\t__x64_sys_close (fs/open.c:1541)\n\tx64_sys_call (arch/x86/entry/syscall_64.c:33)\n\tdo_syscall_64 (arch/x86/entry/common.c:?)\n\tentry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)\n\n\tread to 0xffff88867256ddbb of 1 bytes by task 989 on cpu 14:\n\tunix_stream_sendmsg (net/unix/af_unix.c:2273)\n\t__sock_sendmsg (net/socket.c:730 net/socket.c:745)\n\t____sys_sendmsg (net/socket.c:2584)\n\t__sys_sendmmsg (net/socket.c:2638 net/socket.c:2724)\n\t__x64_sys_sendmmsg (net/socket.c:2753 net/socket.c:2750 net/socket.c:2750)\n\tx64_sys_call (arch/x86/entry/syscall_64.c:33)\n\tdo_syscall_64 (arch/x86/entry/common.c:?)\n\tentry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)\n\n\tvalue changed: 0x01 -> 0x03\n\nThe line numbers are related to commit dd5a440a31fa (\"Linux 6.9-rc7\").\n\nCommit e1d09c2c2f57 (\"af_unix: Fix data races around sk->sk_shutdown.\")\naddressed a comparable issue in the past regarding sk->sk_shutdown.\nHowever, it overlooked resolving this particular data path.\nThis patch only offending unix_stream_sendmsg() function, since the\nother reads seem to be protected by unix_state_lock() as discussed in"
