CVE-2026-64534

The CVE-2026-64534 issue affects the Linux kernel nvmet-tcp path for NVMe over TCP. A data-digest mismatch could trigger an unconditional nvmet_req_uninit() cleanup, which, if the command arrived via the nvmet_tcp_handle_req_failure() path, results in a refcount underflow and a use-after-free tha...

kernel: nvme-tcp: fix UAF when detecting digest errors

A use-after-free vulnerability was found in the Linux kernel in drivers/nvme/host/tcp.c in nvmetcpiowork. This issue can occur when a local user continues to read data after the connection finishes. This flaw allows a malicious user to cause a use-after-free problem...
