Linux Distros Unpatched Vulnerability : CVE-2026-43157

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - octeontx2-af: CGX: fix bitmap leaks The RX/TX flow-control bitmaps rxfcpfvfbmap and txfcpfvfbmap are allocated by cgxlmacinit but never freed in cgxlmacexit...

CVE-2026-43163

A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...
