A patch has been applied to the Linux kernel to fix this issue by modifying the inode eviction logic in evict_inodes(). Users should update to a fixed kernel version to resolve the hung task problem. No additional mitigation actions are indicated beyond applying the official fix.
Description
CVE-2026-98924 is a vulnerability in the Linux kernel's filesystem code that caused repeated scans in the evict_inodes() function during device removal. This issue led to hung tasks when unmounting filesystems after disk removal while still in use. The flaw was due to evict_inodes() restarting inode scans from the head of the list after dropping a lock, causing delays and blocking concurrent unmount attempts. The patch changes the inode eviction logic to avoid repeated scans and prevents the previously reproducible hung task condition.
