Ubuntu has issued an advisory on November 28:
Mageia 7 is also affected.
Updated python-psutil packages fix security vulnerability:
Riccardo Schirone discovered that psutil incorrectly handled certain reference
counting operations. An attacker could use this issue to cause psutil to crash,
resulting in a denial of service, or possibly execute arbitrary code
Updated packages in core/updates_testing:
MGA7-64 Plasma on Lenovo B50
No installation issues.
Used urpmq to find packages to test, picked terminator to test python2-psutil and glances for python3-psutil.
Used strace to check the usage, both programs seemed to perform well, and the trace shows references to the packages under test.
OK for me.
Validating. Advisory in Comment 2.
An update for this issue has been pushed to the Mageia Updates repository.
