CVE-2025-37959 bpf: Scrub packet on bpf_redirect_peer

In the Linux kernel, the following vulnerability has been resolved: bpf: Scrub packet on bpfredirectpeer When bpfredirectpeer is used to redirect packets to a device in another network namespace, the skb isn't scrubbed. That can lead skb information from one namespace to be "misused" in another...

CVE-2025-37922 book3s64/radix : Align section vmemmap start address to PAGE_SIZE

In the Linux kernel, the following vulnerability has been resolved: book3s64/radix : Align section vmemmap start address to PAGESIZE A vmemmap altmap is a device-provided region used to provide backing storage for struct pages. For each namespace, the altmap should belong to that same namespace. ...

CVE-2025-37922

CVE-2025-37922 concerns Linux kernel memory management: when section vmemmap start addresses are misaligned across namespaces, an altmap page may be reused by a different namespace, causing the previous namespace to free a page incorrectly and crash the kernel. The connected documents describe a ...
