CVE-2024-50186

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: A vulnerability in the Linux kernel has been resolved, related to the network code where the sk pointer was not being cleared properly when pf->create fails. This issue was noticed after a previous commit did not fully address the problem, as some pf->create implementations do not use sk common release in their error paths. For example, using arping with an AF PACKET socket can demonstrate the issue if packet create fails. The problem is that future protocols may make the same mistake, so it is easier to explicitly clear the sk pointer upon return from pf->create in sock create.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
