What is CVE-2025-38692?

In the exFAT implementation of the Linux kernel, a vulnerability exists that can lead to an infinite loop caused by file system corruption. This happens when the cluster chain contains a loop, and there are no available entries in the cluster. Specifically, several functions such as exfat_count_dir_entries() and exfat_load_bitmap() can get trapped in an infinite loop under certain conditions. This vulnerability highlights the importance of adding checks to detect and break such loops to maintain system stability and integrity.
