CVE-2024-43887

The CVE-2024-43887 entry relates to the Linux kernel (net/tcp) TCP-AO static key handling. The vulnerability arises because the lifetime of the TCP-AO static_key is tied to the last tcp_ao_info, and, if an RCU grace period is delayed, a CPU may observe a tcp_ao_info that is about to be deallocate...
