CVE-2026-80813

A flaw was found in the Linux kernel's nvmet subsystem. A remote attacker can trigger a NULL pointer dereference in the nvmetexecuteidentifynslist function by issuing a specific Identify command CNS 07h. This vulnerability can lead to a kernel crash, resulting in a Denial of Service DoS for the...

CVE-2026-90228

A flaw was found in the Linux kernel's nvmet subsystem. A remote attacker can trigger a NULL pointer dereference by issuing a specific Identify command CNS 05h, CSI 02h ZNS targeting a file-backed namespace. This vulnerability occurs because the system attempts to access a block device that does...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from a race condition that occurs between the nvmet subsystem and the controller when modifying the maxqid limit, resulting in out-of-bound access and potential memory corruption...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: Do not complete commands twice if nvmetreqinit fails The issue arises when nvmetreqinit calls nvmetreqcomplete internally in case of failures, such as when an unsupported opcode is encountered. This triggers the...
