kernel: cifs: potential buffer overflow in handling symlinks

A buffer overflow vulnerability has been identified in the Linux kernel's Common Internet File System CIFS module, specifically within the parsemfsymlink function. This flaw is caused by insufficient input validation on the linklen value, which dictates the length of a symbolic link. An attacker...
