Lifecycle Timeline
3Description
In the Linux kernel, the following vulnerability has been resolved: gve: Implement settime64 with -EOPNOTSUPP ptp_clock_settime() assumes every ptp_clock has implemented settime64(). Stub it with -EOPNOTSUPP to prevent a NULL dereference.
Analysis
In the Linux kernel, the following vulnerability has been resolved:
gve: Implement settime64 with -EOPNOTSUPP
ptp_clock_settime() assumes every ptp_clock has implemented settime64(). Stub it with -EOPNOTSUPP to prevent a NULL dereference.
Technical Context
A NULL pointer dereference occurs when the application attempts to use a pointer that has not been initialized or has been set to NULL.
Remediation
Add NULL checks before pointer dereference operations. Use static analysis to identify potential NULL pointer issues. Enable compiler warnings.
