CVE-2026-52969

CVE-2026-52969 affects the Linux kernel KVM component. The vulnerability stems from an unchecked u64 addition in kvm_reset_dirty_gfn(), where the guard if (!memslot || (offset + __fls(mask)) >= memslot->npages) can be bypassed due to offset being 64‑bit. This can allow an out-of-bounds load...

CVE-2026-52969 KVM: Reject wrapped offset in kvm_reset_dirty_gfn()

In the Linux kernel, the following vulnerability has been resolved: KVM: Reject wrapped offset in kvmresetdirtygfn kvmresetdirtygfn guards the gfn range with if !memslot || offset + flsmask = memslot-npages return; but offset is u64 and the addition is unchecked. The check can be silently bypasse...

CVE-2026-56208

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...

Your Privacy My Cloak: Backdoor Attacks on Differentially Private Federated Learning

Prior research suggests that differential privacy DP inherently enhances the robustness of federated learning FL against backdoor attacks. In this paper, we challenge this assumption. Through an empirical analysis of two baseline attack strategies, we uncover a fundamental tension in DP-FL: while...
