CVE-2026-23376

A flaw was found in the Linux kernel's nvmet-fcloop component. This vulnerability occurs due to incorrect handling of resource freeing when the remote port state is not online. Specifically, the fcloopt2hxmtlsrsp routine fails to check the remoteport-portstate before calling a done callback, whic...

CVE-2026-23376

CVE-2026-23376 affects the Linux kernel nvmet-fcloop component. The vulnerability arises from not checking remoteport port_state before freeing resources in the fcloop_t2h_xmt_ls_rsp path, where lsrsp resources may be freed incorrectly if the remote port is not online. The fix updates fcloop_t2h_...
