What it is

In the Linux kernel, the following vulnerability has been resolved:

ptp: ocp: Fix board ID over-read

The EEPROM board ID is a fixed 13-byte field and is not guaranteed to

contain a NUL terminator. Passing it directly to

devlink_info_version_fixed_put() treats it as a C string and may read

beyond the field.

Format at most OCP_BOARD_ID_LEN bytes into the existing local buffer

before reporting the ID. Use a precision limit because the snprintf()

output size alone does not bound the source string scan.
