CVE-2026-89925

A flaw was found in KVM's guest debug handling within the Linux kernel. A local user, by repeatedly calling KVMSETGUESTDEBUG, can trigger a memory leak. This occurs because the bpdata is not freed after a successful debug operation. Over time, this can lead to resource exhaustion and a Denial of...

CVE-2026-89925

CVE-2026-89925 affects the Linux kernel KVM s390 module. The root cause is a memory leak in the guest debug handling path: bp_data is freed via kfree() only in the error case of KVM_SET_GUEST_DEBUG, so every successful KVM_SET_GUEST_DEBUG call leaks the allocation. The practical impact is a per-c...
