- Summary
- CVE-2024-41082 affecting package kernel 6.6.126.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvme-fabrics: use reserved tag for reg read/write command
In some scenarios, if too many commands are issued by nvme command in the same time by user tasks, this may exhaust all tags of adminq. If a reset (nvme reset or IO timeout) occurs before these commands finish, reconnect routine may fail to update nvme regs due to insufficient tags, which will cause kernel hang forever. In order to workaround this issue, maybe we can let regread32()/regread64()/regwrite32() use reserved tags. This maybe safe for nvmf:
- For the disable ctrl path, we will not issue connect command
- For the enable ctrl / fw activate path, since connect and reg_xx() are called serially.
So the reserved tags may still be enough while reg_xx() use reserved tags.
