TIMELINE Oct 7 Reserved by Linux Oct 7 Published (CNA: Linux) Aug 4 RESCORED — CVE-2023-53643 (Linux). CVSS 7.8 → 5.5 (NVD).
In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: don't access released socket during error recovery While the error recovery work is temporarily failing reconnect attempts, running the 'nvme list' command causes a kernel NULL pointer dereference by calling getsockname() with a released socket. During error recovery work, the nvme tcp socket is released and a new one created, so it is not safe to access the socket without proper check.
