Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue arises when too many commands are issued by the nvme command at the same time by user tasks, potentially exhausting all tags of admin q. If a reset or IO timeout occurs before these commands finish, the reconnect routine may fail to update nvme regs due to insufficient tags, causing the kernel to hang forever. To address this, using reserved tags for reg read32(), reg read64(), and reg write32() is proposed as a workaround. This approach is considered safe for nvmf, particularly in scenarios where connect and reg xx() are called serially.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
