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...

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...

Siemens SIMATIC Devices Improper Locking (CVE-2024-50210)

In the Linux kernel, the following vulnerability has been resolved: posix-clock: posix-clock: Fix unbalanced locking in pcclocksettime If getclockdesc succeeds, it calls fget for the clockid's fd, and get the clk-rwsem read lock, so the error path should release the lock to make the lock balance...

SUSE CVE-2024-50195

In the Linux kernel, the following vulnerability has been resolved: posix-clock: Fix missing timespec64 check in pcclocksettime As Andrew pointed out, it will make sense that the PTP core checked timespec64 struct's tvsec and tvnsec range before calling ptp-info-settime64. As the man manual of...
