What to do
AI-suggested
The issue has been resolved by modifying the nvme-fabrics code to use reserved tags for register read/write commands, preventing tag exhaustion during reconnect. Users should apply the official Linux kernel updates that include this fix. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's nvme-fabrics subsystem can cause a kernel hang when too many NVMe admin commands exhaust available tags and a reset occurs before commands complete. This happens because the reconnect routine fails to update NVMe registers due to insufficient tags. The issue is mitigated by using reserved tags for register read/write commands to avoid tag exhaustion.
