Name of the Vulnerable Software and Affected Versions Linux kernel version 6.8.0-rc3

Description The issue is related to a potential buffer overflow in the fscanf function, which may occur when the mount point variable is used. The warning is reported by clang, indicating that the destination buffer in argument 3 has a size of 1024, but the corresponding specifier may require a size of 1025. To avoid the overflow, the mount point variable size should be increased to MAX PATH+1.

Recommendations Increase the mount point variable size to MAX PATH+1 to avoid the overflow.
