kernel: infinite loop in update_blocked_averages() in kernel/sched/fair.c leading to denial of service
The CFS Linux kernel scheduler mishandles handling of leaf cfsrq's in the kernel/sched/fair.c code, which allows a local unprivileged attacker to cause a denial of service DoS by entering an infinite loop in updateblockedaverages function by inducing a high load on a system. Due to the nature of...
