Oracle Linux: CVE-2024-41081: ELSA-2024-12782: Unbreakable Enterprise kernel-container security update (IMPORTANT) (Multiple Advisories)
Description
In the Linux kernel, the following vulnerability has been resolved: ila: block BH in ila_output() As explained in commit 1378817486d6 ("tipc: block BH before using dst_cache"), net/core/dst_cache.c helpers need to be called with BH disabled. ila_output() is called from lwtunnel_output() possibly from process context, and under rcu_read_lock(). We might be interrupted by a softirq, re-enter ila_output() and corrupt dst_cache data structures. Fix the race by using local_bh_disable(). A race condition flaw was found in the Linux kernel's IP Last Anomaly (ILA) subsystem. This issue occurs when the `ila_output()` function, called from `lwtunnel_output()` in process context and under RCU read lock, could be interrupted by a softirq, leading to potential corruption of `dst_cache` data structures.
