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.
