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...
