AZL-101328 CVE-2026-89968 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: reject unsolicited H2CData PDUs nvmettcphandleh2cdatapdu accepts an H2CData PDU after only checking that its TTAG is a valid in-range command index and that the command's data buffers are mapped. It never checks that t...

EUVD-2026-80573

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: check the data direction of a C2HData PDU nvmetcphandlec2hdata finds the request by command id and checks that it has a payload, but it does not check that the command asked for data to be read. A controller that answer...

CVE-2026-89973

CVE-2026-89973 affects the nvme-tcp driver in the Linux kernel. The function nvme_tcp_handle_c2h_data() validates a C2HData PDU's command ID and payload presence but does not check the data direction . A malicious or buggy NVMe controller can trigger a kernel warning (WARN_ON_ONCE in _copy_to_ite...

CVE-2026-89969 nvmet-tcp: fix out-of-bounds write when receiving an over-long PDU

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix out-of-bounds write when receiving an over-long PDU nvmettcptryrecvpdu reads a PDU header into the fixed 128-byte queue-pdu union, then computes the remaining payload length as queue-left = hdr-hlen - queue-offset ...

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...

CVE-2026-80225

A flaw was found in Unbound. A malicious actor can exploit a vulnerability in the TCP/DoT reading procedure, which lacks a limit on consecutive reads. By continuously streaming distinct uncached names over a TCP/DoT connection, an attacker can monopolize a worker's event loop. This can lead to a...

CVE-2026-81634

In NLnet Labs Unbound up to and including 1.26.0, a 255 length query name with a large TCP response can lead to a heap buffer overflow during the RRSet canonicalisation routine. This is caused by missing to add the first owner name into the buffer length check. A malicious actor operating a...
