Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: posix-clock: The missing timespec64 check in pcclocksettime has been fixed. As Andrew pointed out, it makes sense that the PTP core checks the tvsec and tvnsec fields of the timespec64 structure before calling ptp-info-settime64...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: posix-clock: posix-clock: Fixed unbalanced locking in pcclocksettime. If getclockdesc succeeds, it calls fget for the fd of the clockid. It also acquires a read lock on clk-rwsem. Therefore, the error path should release the lock...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gve: Implement settime64 with -EOPNOTSUPP The ptpclocksettime function assumes that every ptpclock has implemented settime64. Implementing settime64 with -EOPNOTSUPP prevents a NULL derefrence...

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.

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel, which stems from an unimplemented settime64 in the ptpclocksettime function in the iavf driver, which could lead to a null...

CVE-2025-40298

CVE-2025-40298 concerns the Linux kernel. The root cause is that ptp_clock_settime() assumes every ptp_clock implements settime64(), which could lead to a NULL dereference. The fix implements settime64 in gve and stubs ptp_clock_settime() with -EOPNOTSUPP for clocks that do not support it, preven...

kernel: posix-clock: Fix missing timespec64 check in pc_clock_settime()

A flaw was found in the Linux kernel's posix-clock component. A local attacker with low privileges could exploit a missing validation check in the pcclocksettime function. By providing invalid time values, such as a negative tvsec or an out-of-range tvnsec, the attacker could cause certain driver...
