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 ...
