GHSA-q7ch-p7wx-7pf8 PUBLISHED CVSS 5.5 MEDIUM

Record from GitHub Advisory Database · Published July 29, 2024

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().
