CVE-2025-68350

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> exfat: fix divide-by-zero in exfat_allocate_bitmap<br /> <br /> The variable max_ra_count can be 0 in exfat_allocate_bitmap(),<br /> which causes a divide-by-zero error in the subsequent modulo operation<br /> (i % max_ra_count), leading to a system crash.<br /> When max_ra_count is 0, it means that readahead is not used. This patch<br /> load the bitmap without readahead.
