Description
A use-after-free vulnerability was identified and fixed in the Linux kernel NVMe driver affecting version 5.9. The issue occurred when an I/O passthrough command was sent through a multipath namespace head after the controller path that created the head was removed, causing a kernel slab-use-after-free error. The fix involved moving the log cache to the subsystem level to maintain valid log pointers until subsystem release.
