Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the ptp clock settime() function. This function incorrectly assumes that every precision time protocol (PTP) clock has implemented the settime64() function, potentially leading to a NULL dereference. The issue is addressed by stubbing the function with -EOPNOTSUPP to prevent this dereference. The fix mirrors a previous commit related to gve: Implement settime64 with -EOPNOTSUPP.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
