Oracle Linux: CVE-2023-6932: ELSA-2024-2394: kernel security, bug fix, and enhancement update (IMPORTANT) (Multiple Advisories)
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. A race condition has been discovered in the Linux kernel's Internet Group Management Protocol (IGMP) implementation. This vulnerability may enable an attacker to provoke an application crash or potentially escalate privileges locally. By exploiting the race condition, an adversary could disrupt the normal operation of affected systems, leading to service disruption or, in the worst case, unauthorized access to sensitive resources.
