Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack. The vulnerability is related to the
exfat get uniname from ext entry() function in the fs/exfat/dir.c module, which is associated with accessing memory beyond the allocated buffer.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
