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().

Affected configurations

• linux linux kernel (>= 4.10 < 4.19.319) • linux linux kernel (>= 4.20 < 5.4.281) • linux linux kernel (>= 5.5 < 5.10.223) • linux linux kernel (>= 5.11 < 5.15.164) • linux linux kernel (>= 5.16 < 6.1.101) • linux linux kernel (>= 6.2 < 6.6.42) • linux linux kernel (>= 6.7 < 6.9.11) • linux linux kernel 6.10
