**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the f2fs file system in the Linux kernel. During recovery, if FAULT BLOCK is on, it is possible that `f2fs reserve new block()` will return -ENOSPC, which may trigger a panic. Additionally, if the fault injection rate is 1 and only FAULT BLOCK fault type is on, it may encounter a deadloop in the block reservation loop. The problem can be fixed by removing `bug on()` to avoid panic and limiting the loop count of block reservation to avoid potential deadloop. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
