CVE-2023-53585

CVE-2023-53585 : In the Linux kernel, a bug in bpf_sk_assign could leak a refcount when a newly created unhashed UDP socket is bound after being added to a sockmap. The issue arises because bpf_sk_assign may be invoked in an RCU-critical section before the sk’s final state (SOCK_RCU_FREE) is appl...
