The vulnerability of the `nvme_map_user_request()` function in the drivers/nvme/host/ioctl.c file of the NVME driver for the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the nvmemapuserrequest function in the drivers/nvme/host/ioctl.c file of the NVME driver for the Linux operating system is related to the failure to release resources after their useful life has expired. Exploiting this vulnerability could allow an attacker to cause a service...

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...
