CVE-2025-68351 exfat: fix refcount leak in exfat_find

In the Linux kernel, the following vulnerability has been resolved: exfat: fix refcount leak in exfatfind Fix refcount leaks in exfatfind related to exfatgetdentryset. Function exfatgetdentryset would increase the reference counter of es-bh on success. Therefore, exfatputdentryset must be called...

CVE-2025-68351

The CVE-2025-68351 issue is in the Linux kernel exfat code, specifically a refcount leak in exfat_find. The root cause is that exfat_get_dentry_set increments es->bh on success but the corresponding exfat_put_dentry_set may not be consistently invoked, leading to leaks. The patch relocates two...

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...
