CVE-2026-23450

CVE-2026-23450 (Linux kernel): The issue stems from a race in the SMC TCP path (net/smc) where, during close of an SMC listen socket, sk_user_data can be NULL or the smc_sock freed, causing a NULL dereference or use-after-free in smc_tcp_syn_recv_sock() when accessed under rcu/protected context. ...

Oracle Linux 10 : kernel (ELSA-2026-2721)

The remote Oracle Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-2721 advisory. - nvme-tcp: fix NULL pointer dereferences in nvmettcpbuildpduiovec CKI Backport Bot RHEL-144335 CVE-2026-22998 - smc: Fix use-after-free in...

CVE-2023-53781

CVE-2023-53781 affects the Linux kernel: a use-after-free in tcp_write_timer_handler() can occur when SMC creates a kernel socket (__smc_create()) and the socket is freed without stopping TCP timers if the parent SMC socket’s sk_state isn’t TCP_CLOSE. The issue arises because inet_csk_destroy_soc...

Linux Kernel smc_inet6_protosw Structure Buffer Overflow DoS

The vulnerability of the “smcinet6protosw” module’s definition of the structure in the “net/smc/smcinet.c” file within the SMC protocol family of the Linux operating system is related to the use of pointers. Exploiting this vulnerability could allow an attacker to cause a service failure...
