      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: fix use-after-free in smc_rx_pipe_buf_release()\n\nsmc_rx_splice() hands RMB pages to a pipe and takes a socket reference\nper entry so the smc_sock stays alive until the reader finishes. The\nconnection does not: a concurrent close runs smc_conn_free(), which\nreleases the receive buffer back to the link group pool.\n\nsmc_rx_pipe_buf_release() tests sk_state before taking the socket lock.\nThe state can change between the test and the lock, and\nsmc_rx_update_cons() then dereferences conn->rmb_desc and walks\nconn->lgr, which smc_conn_free() has already released. On the\nis_reg_err path smcr_buf_unuse() frees the descriptor outright, so\nthis is a use-after-free.\n\nTake the socket lock first and test conn->freed instead.\nsmc_conn_free() sets that flag before releasing anything, and every\ncaller holds the socket lock. The two paths exclude each other: either\nthe pipe release runs first with everything valid, or it sees the flag\nand skips the update.",
