CVE-2025-40287

CVE-2025-40287 : In the Linux kernel exFAT code, an improper validation of dentry.stream.valid_size can cause an infinite loop, enabling a Denial-of-Service (DoS) when issuing SYS_openat, SYS_ftruncate, or SYS_pwrite64 on a malformed exFAT dentry. Root cause: the size check in exfat_find() did no...
