Last modified
CVE-2023-6932 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
