CVE-2026-90432
CVE-2026-90432 affects the Linux kernel 's sched_ext (scheduler extension) subsystem. The vulnerability is in the hardlockup handler (scx_hardlockup()), which deferred the abort to an irq_work—originally needed because exit claiming required scx_sched_lock and couldn't run from NMI. Now that clai...

SUSE 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
A flaw was found in the Linux kernel's real-time RT scheduler. Under specific heavy load conditions, a vulnerability in the rtonextcpu function can cause a CPU to repeatedly interrupt itself. This leads to a CPU hardlockup, resulting in a Denial of Service DoS for the system. This issue can be...

CVE-2026-45919
CVE-2026-45919 relates to Linux kernel sched/rt self-IPI loops caused by LB on CPU0. A patch fixes the issue by filtering out the initiating CPU in rto_next_cpu to prevent self-IPIs and CPU hardlockups. Public OSV entries show Root:Ubuntu patches (e.g., ROOT-OS-UBUNTU-2404-CVE-2026-45919 and ROOT...
