AI-Generated

A vulnerability in the Linux kernel affects the handling of the EEPROM board ID, which is a fixed 13-byte field that may not contain a NUL terminator. This oversight can lead to potential over-read issues when the ID is processed as a C string, risking memory corruption or information leakage. Organizations utilizing Linux systems, particularly those relying on the affected PTP (Precision Time Protocol) implementations, should prioritize addressing this vulnerability to mitigate potential security risks.

Original NVD Description

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.
