Linux Distros Unpatched Vulnerability : CVE-2026-89545

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sunrpc: defer rqargp and rqresp free until after RCU grace period svcrqstfree frees rqstp-rqargp and rqstp-rqresp synchronously via kfree, but defers the rqstp...

CVE-2026-89685

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A clock domain mismatch in the clientsstillreclaiming function allows a remote attacker to indefinitely hold the server in a grace period. By sending specific CLAIMPREVIOUS OPEN requests, an attacker can block all...

CVE-2026-89756

A flaw was found in the Linux kernel. When performing memory migration on KVM Kernel-based Virtual Machine hosts, the migratepagesbatch function fails to report RCU Read-Copy Update tasks quiescent states during large batch unmapping operations. This oversight causes the migrating task to become ...

CVE-2026-89756

In the Linux kernel, the following vulnerability has been resolved: mm/migrate: report RCU-tasks quiescent states in migratepagesbatch migratepagesbatch unmaps each folio before moving it, and every unmap runs the mmunotifier invalidate callbacks. On KVM hosts trytomigrate ends up in...

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...
