  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nptp: ocp: Fix board ID over-read\n\nThe EEPROM board ID is a fixed 13-byte field and is not guaranteed to\ncontain a NUL terminator. Passing it directly to\ndevlink_info_version_fixed_put() treats it as a C string and may read\nbeyond the field.\n\nFormat at most OCP_BOARD_ID_LEN bytes into the existing local buffer\nbefore reporting the ID. Use a precision limit because the snprintf()\noutput size alone does not bound the source string scan.",
