kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page

A flaw was found in the Linux kernel's nvmet subsystem. An unauthenticated remote attacker could exploit an out-of-bounds heap read vulnerability in the Discovery Get Log Page function. By sending a specially crafted request with a manipulated offset, an attacker could read sensitive kernel memor...

CVE-2025-38658 nvmet: pci-epf: Do not complete commands twice if nvmet_req_init() fails

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: Do not complete commands twice if nvmetreqinit fails Have nvmetreqinit and req-execute complete failed commands. Description of the problem: nvmetreqinit calls nvmetreqcomplete internally upon failure, e.g.,...

CVE-2025-38658

CVE-2025-38658 affects the Linux kernel nvmet PCI-EPF path. The issue occurs when nvmet_req_init() fails (e.g., on an unsupported opcode), because __nvmet_req_complete() can trigger queue_response which may call nvmet_pci_epf_complete_iod(), and nvmet_pci_epf_exec_iod_work() may also invoke the s...

CVE-2025-38405 nvmet: fix memory leak of bio integrity

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix memory leak of bio integrity If nvmet receives commands with metadata there is a continuous memory leak of kmalloc-128 slab or more precisely bio-biintegrity. Since commit bf4c89fc8797 "block: don't call biouninit from...
