CVE-2024-53093 Information

Description

In the Linux kernel the following vulnerability has been resolved:

nvme-multipath: defer partition scanning

We need to suppress the partition scan from occuring within the controller’s scan_work context. If a path error occurs here the IO will wait until a path becomes available or all paths are torn down but that action also occurs within scan_work so it would deadlock. Defer the partion scan to a different context that does not block scan_work.
