MEDIUM 4.7EPSS 7.16%
Does this matter?
Lower severity and a low EPSS score (7.16%). Track it; it rarely justifies an emergency change on its own.
Description
A time-of-check-time-of-use (TOCTOU) race condition vulnerability was found in networkd-dispatcher. This flaw exists because there is a certain time between the scripts being discovered and them being run. An attacker can abuse this vulnerability to replace scripts that networkd-dispatcher believes to be owned by root with ones that are not.
