CVE-2025-68350 exfat: fix divide-by-zero in exfat_allocate_bitmap

In the Linux kernel, the following vulnerability has been resolved: exfat: fix divide-by-zero in exfatallocatebitmap The variable maxracount can be 0 in exfatallocatebitmap, which causes a divide-by-zero error in the subsequent modulo operation i % maxracount, leading to a system crash. When...

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...
