The vulnerabilities of the functions nvmet_tcp_build_pdu_iovec() and nvmet_tcp_handle_req_failure() in the Linux kernel’s drivers/nvme/target/tcp.c module allow attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerabilities of the functions nvmettcpbuildpduiovec and nvmettcphandlereqfailure in the driver/nvme/target/tcp.c module of the Linux kernel are related to error handling flaws. Exploiting these vulnerabilities allows a remote attacker to compromise the confidentiality, integrity, and...
