Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iavf: Implement settime64 with -EOPNOTSUPP The ptpclocksettime function assumes that every ptpclock has implemented settime64. By using -EOPNOTSUPP as a stub, we prevent a NULL derefrence from occurring. This fix is similar to th...

CVE-2026-31396

Summary: CVE-2026-31396 affects the Linux kernel’s net/macb and PTP clock subsystem. The root cause is a use-after-free in ptp_clock_index() when the PTP clock is accessed via get_ts_info while the interface’s PTP clock object has been deregistered. This allows a local attacker to trigger a crash...
