CVE-2026-89480

CVE-2026-89480 affects the NVMe-TCP driver in the Linux kernel. The function nvme_tcp_recv_data() completes a read request once the current C2HData PDU is consumed, but no mechanism compares the total bytes received against the length requested by the command. A malicious or faulty NVMe controlle...

The vulnerability of the nvme_free_host_mem_multi() function in the driver/nvme/host/pci.c module of the Linux kernel’s NVME driver allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the nvmefreehostmemmulti function in the nvme/host/pci.c driver module of the Linux operating system is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected...

kernel: nvmet-auth: validate reply message payload bounds against transfer length

A flaw was found in the Linux kernel's nvmet-auth component. A remote attacker, by sending a specially crafted NVMe-oF NVMe over Fabrics authentication reply message, can cause an out-of-bounds read in the kernel's memory. This vulnerability, exploitable pre-authentication, can lead to the...

CVE-2026-80862

This Linux kernel vulnerability affects the nvme-tcp subsystem. The page_frag_cache is used to preallocate PDU buffers for preallocated block device requests, but since block devices are created in parallel threads, the cache is accessed in a thread-unsafe manner. This leads to incorrect refcount...
