CVE-2025-68350

The CVE-2025-68350 issue affects the Linux kernel exfat code path and is caused by a division by zero in exfat_allocate_bitmap when max_ra_count can be 0. This occurs during a modulo operation (i % max_ra_count) and is triggered when readahead is not used. A patch was applied to load the bitmap w...
