In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Clear __hyp_running_vcpu when flushing the pKVM hyp vCPU flush_hyp_vcpu() copies the host vCPU context into the hyp's private vCPU on every run. ctxt_to_vcpu() expects a guest context to have a NULL __hyp_running_vcpu, which is only ever set on the host context, so that it resolves the vCPU via container_of(). While …

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Bound used_lrs when flushing the pKVM hyp vCPU flush_hyp_vcpu() copies the host vGIC state into the hyp's private vCPU on every run. The vGIC list register save and restore use used_lrs as their loop bound and expect it to stay within the number of implemented list registers. While this is generally the case, flush_h…

The WPForms Pro plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.10.1.1 via the ajax_chunk_upload_finalize function. This is due to the file type validation occurring after chunk metadata and file contents have already been written to disk, and the assembled file not being deleted upon validation failure. This makes it possible for unauthenticated…

Redis before 8.8.0, in the unusual case where an authenticated attacker can execute RESTORE, allows remote code execution via a RESTORE payload where the same NACK (pending entry) is referenced by more than one consumer, because deleting both consumers via XGROUP DELCONSUMER leads to a double free. NOTE: this issue exists because of an incomplete fix for CVE-2026-25243.
