high Nessus Plugin ID 146293



The remote openSUSE host is missing a security update.


The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349).
