In the Linux kernel, the following vulnerability has been resolved: LoongArch: Avoid preempt count underflow without probe LoongArch uses break 11 for the breakpoint placed after an instruction that Kprobes executes out of line. Since userspace can issue the same break instruction, dobp can reach...

CVE-2026-89902

This Linux kernel vulnerability affects the LoongArch kprobe subsystem. Because LoongArch uses break 11 for kprobe breakpoints, an ordinary userspace breakpoint can reach kprobe_singlestep_handler() with no active probe. The handler calls preempt_enable_no_resched() before checking for a probe, c...

CVE-2026-89756

CVE-2026-89756 is a Linux kernel flaw in migrate_pages_batch() (mm/migrate). On PREEMPTION kernels, the loop's cond_resched() call is a no-op, and involuntary preemption does not constitute a Tasks-RCU quiescent state . When large page-migration batches run on KVM hosts , the expensive tdp_mmu_za...
