NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-core package and not the kernel-zfcpdump-modules-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.

A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.

We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.
