kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

CVE-2026-90230

A flaw was found in the Linux kernel's nvmet subsystem. A remote attacker, by sending a specially crafted NVMe-oF NVMe over Fabrics in-band authentication negotiation message with an invalid transfer length or identifier lengths, could trigger a heap out-of-bounds read in the nvmetauthnegotiate...

CVE-2026-90229

A flaw was found in the Linux kernel's NVMe Apple driver. When an NVMe controller fails to initialize and is subsequently removed, the driver does not properly destroy the associated admin queue. This oversight can lead to a kernel panic, effectively causing a denial of service DoS on the affecte...

Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-8631-1)

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8631-1 advisory. Siebe Devroe, Hlose Gollier, and Mathy Vanhoef discovered that the WiFi implementation in the Linux kernel did not properly handle aggregated...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

ROS-20261012-73-0050

The vulnerability of the nvmeirqcheck function in the drivers/nvme/host/pci.c module of the Linux NVME driver is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: nvme-tcp: reject a read that transferred too few bytes

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...

kernel: nvme-tcp: fix host memory disclosure on R2T for a read command

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

kernel: nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express input/output control ioctl handling. An unprivileged local user could exploit this vulnerability by bypassing access checks in the NVMEIOCTLSUBMITIO function. This allows them to perform unauthorized I/O operations on a...

kernel: nvme: add missing SRCU grace period in error path

A flaw was found in the NVMe Non-Volatile Memory Express driver of the Linux kernel. The nvmeallocns function's error handling path fails to wait for all SRCU Sleepable Read-Copy Update readers to complete before freeing a namespace structure. This oversight allows a concurrent reader to access a...

CVE-2026-80811

A flaw was found in the Linux kernel's iouring/cmd component. This vulnerability allows for a memory leak due to iovec arrays not being properly freed when asynchronous commands are not recycled. An attacker could potentially exploit this by triggering specific workloads, such as NVMe passthrough...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

Oracle Linux 8 : kernel (ELSA-2026-75747)
