CVE-2023-6932
Here are the titles: 1. Linux Kernel Igmp IPv4 Use-After-Free Vulnerability 2. Linux Kernel RCU Timer Race Condition Vulnerability
Description
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.
