Vulnerability Title
Kernel: exfat: stack overflow in exfat_get_uniname_from_ext_entry
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in the exFAT driver of the Linux kernel.

Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack.
