CVE-2026-45919 sched/rt: Skip currently executing CPU in rto_next_cpu()

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...

PT-2026-43786

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Real-Time RT load balancing mechanism where a CPU can enter an infinite self-Inter-Processor Interrupt IPI loop, leading to a CPU hardlockup. This occurs when a CP...

SUSE CVE-2026-43392

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix starvation of scxenable under fair-class saturation During scxenable, the READY - ENABLED task switching loop changes the calling thread's schedclass from fair to ext. Since fair has higher priority than ext,...
