"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvsock/bpf: return early if transport is not assigned\n\nSome of the core functions can only be called if the transport\nhas been assigned.\n\nAs Michal reported, a socket might have the transport at NULL,\nfor example after a failed connect(), causing the following trace:\n\n BUG: kernel NULL pointer dereference, address: 00000000000000a0\n #PF: supervisor read access in kernel mode\n #PF: error_code(0x0000) - not-present page\n PGD 12faf8067 P4D 12faf8067 PUD 113670067 PMD 0\n Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI\n CPU: 15 UID: 0 PID: 1198 Comm: a.out Not tainted 6.13.0-rc2+\n RIP: 0010:vsock_connectible_has_data+0x1f/0x40\n Call Trace:\n vsock_bpf_recvmsg+0xca/0x5e0\n sock_recvmsg+0xb9/0xc0\n __sys_recvfrom+0xb3/0x130\n __x64_sys_recvfrom+0x20/0x30\n do_syscall_64+0x93/0x180\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nSo we need to check the `vsk->transport` in vsock_bpf_recvmsg(),\nespecially for connected sockets (stream/seqpacket) as we already\ndo in __vsock_connectible_recvmsg()."
