In the Linux kernel, the following vulnerability has been resolved: net/smc: fix use-after-free in smcrxpipebufrelease smcrxsplice hands RMB pages to a pipe and takes a socket reference per entry so the smcsock stays alive until the reader finishes. The connection does not: a concurrent close run...

CVE-2026-80982

CVE-2026-80982 is a use-after-free in the Linux kernel's SMC (Shared Memory Communications) network protocol (net/smc). The root cause is a race condition in smc_rx_pipe_buf_release(): it checks sk_state before acquiring the socket lock, so a concurrent smc_conn_free() can release the connection ...
