In the Linux kernel, the following vulnerability has been resolved: KVM: s390 – Fixed a memory leak in guest debug handling. The bpdata is only freed in the error case by using kfreebpdata. Every successful call to KVMSETGUESTDEBUG will cause the bpdata to be leaked...

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...
