CVE-2026-45919

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Skip currently executing CPU in rtonextcpu CPU0 becomes overloaded when hosting a CPU-bound RT task, a non-CPU-bound RT task, and a CFS task stuck in kernel space. When other CPUs switch from RT to non-RT tasks, RT load...

CVE-2026-45919

The CVE-2026-45919 entry covers a Linux kernel vulnerability in the sched/rt path where CPU0 becomes overloaded during RT and non-RT task interactions, triggering self-IPI loops during RT load balancing. The root cause is that rto_next_cpu() could restart its search from -1 due to increments to r...
