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...

Configure Audit Rules for Time Changes

The system time is essential for the normal running of services. The system time can be changed through synchronization with the time server and manual operations of administrators. The latter is prone to attacks because attackers can change the system time to invalidate some protection policies...
