kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. When a data digest mismatch occurs, a reference count underflow can happen due to an unconditional cleanup call. This issue can lead to a use-after-free condition and ultimately result in a permanent workqueue deadlock...

CVE-2026-89969

CVE-2026-89969 is a critical out-of-bounds write in the Linux kernel's NVMe over TCP target (nvmet-tcp) module. The function nvmet_tcp_try_recv_pdu() reads PDU data into a fixed 128-byte buffer without bounding the payload length against the buffer size. When a header digest has been negotiated a...

CVE-2026-89968

CVE-2026-89968 affects the Linux kernel's NVMe/TCP target (nvmet-tcp). The function nvmet_tcp_handle_h2c_data_pdu() accepts an H2CData PDU without verifying that the target has actually solicited the data via an R2T for that command. A remote host can exploit this by sending an H2CData PDU before...
