CVE-2026-74603

HIGH CVSS 3.1: 7.1 EPSS 0.13%

Linux
Parameter Value
CVSS 7.1 (HIGH)
Vendor Linux
Public PoC No

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.
