CVE-2025-40307

CVE-2025-40307 affects the Linux kernel's exfat implementation. The issue arises from invalid validation of cluster allocation bits in the allocation bitmap, allowing a cluster (potentially 6 when the start cluster is 6) to be allocated during mkdir, which can lead to deletion/reallocation of dir...

CVE-2025-40287

An infinite loop vulnerability was found in the exFAT filesystem driver in the Linux kernel. The exfatfind function does not validate if dentry.stream.validsize is negative. A malformed exFAT filesystem with such entries causes the kernel to hang during file operations like open, truncate, or wri...
