kernel: udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port()

In the Linux kernel, the following vulnerability has been resolved: udp: Set SOCKRCUFREE earlier in udplibgetport. syzkaller triggered the warning 0 in udpv4earlydemux. In udpv46earlydemux and sklookup, we do not touch the refcount of the looked-up sk and use sockpfree as skb-destructor, so we...

kernel: af_unix: Fix garbage collector racing against connect()

A flaw was found in the Linux kernel, where the management of inter-process communication uses AFUNIX sockets. The issue arises from a race condition where a partially initialized socket with specific permissions carrying SCMRIGHTS is improperly handled during garbage collection. This situation...

kernel: vsock: remove vsock from connected table when connect is interrupted by a signal

A vulnerability was found in the Linux kernel's vsock subsystem's vsockstreamconnect function where improper handling of the socket state can lead to the connected table's list being corrupted. This occurs when a signal interrupt occurs and resets the socket's state without removing it from the...

kernel: SUNRPC: lock against ->sock changing during sysfs read

A vulnerability was found in the Linux kernel's SUNRPC component, where a race condition exists during sysfs read operations due to improper handling of the -sock pointer. If the mutex -recvmutex is not held, -sock may change asynchronously, leading to a potential kernel oops. This vulnerability...

kernel: net: do not leave a dangling sk pointer, when socket creation fails

A vulnerability was found in the Linux kernel's networking component in the sockrelease function, where a dangling pointer can occur when socket creation fails. This happens when a reference to the socket is not cleared, leading to a use-after-free condition...
