A recently disclosed Linux-kernel vulnerability, tracked as CVE-2025-21945, fixes a subtle but consequential use‑after‑free in the in‑kernel SMB server (ksmbd) — the bug can reliably produce kernel instability and therefore presents a high availability risk for any system whose kernel includes...

Google’s widely used RPC stack has been rocked by a high‑impact denial‑of‑service flaw that can be triggered remotely against a range of gRPC deployments on POSIX platforms: CVE‑2023‑4785 arises from missing error handling in the gRPC TCP server and allows a remote attacker to exhaust server...

Libvirt has been assigned CVE-2024-1441 for an off-by-one bug in the udevListInterfacesByStatus() function that can be triggered by an unprivileged client to crash the libvirt daemon, producing a denial-of-service condition for virtualization management on affected systems. Background Libvirt is...

The discovery of CVE-2024-2494 exposed a simple but dangerous class of bug inside libvirt’s RPC deserialization: a negative array length read from an attacker-controlled RPC message can be passed to GLib’s g_new0 allocator and — because the negative value is interpreted as a very large unsigned...

Siemens has released an urgent security update for NX after researchers discovered a cluster of high‑severity file‑parsing vulnerabilities in the way the product reads CGM (Computer Graphics Metafile) files; the flaws—tracked as CVE‑2026‑22923, CVE‑2026‑22924 and CVE‑2026‑22925—can cause...

A newly cataloged vulnerability, tracked as CVE-2026-20927, has been posted in Microsoft's Update Guide as a denial‑of‑service (DoS) flaw affecting the Windows SMB Server component; the advisory and the vendor‑confidence classification published alongside it change the operational calculus for...
