CVE-2026-74603 in Linux
要約
〜によって MITRE • 2026年08月22日
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.
