CVE-2023-52454

CVE-2023-52454 affects the Linux kernel nvmet-tcp path. A host sending an H2CData command with an invalid DATAL can cause a kernel panic or a NULL pointer dereference in nvmet_tcp_build_pdu_iovec(), as evidenced by the crash trace in nvmet_tcp_io_work. The fix raises a fatal error when DATAL is n...

kernel: NULL pointer dereference in nvmet_tcp_execute_request

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service...

kernel: use after free in nvmet_tcp_free_crypto in NVMe

A use-after-free vulnerability was found in drivers/nvme/target/tcp.c in nvmettcpfreecrypto due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead t...
