free5GC's NEF nnef-pfdmanagement API is unauthenticated; forged bearer tokens can read PFD data and create/delete PFD subscriptions

Summary free5GC's NEF mounts the nnef-pfdmanagement route group without inbound OAuth2/bearer-token authorization. A network attacker who can reach NEF on the SBI can use a forged or arbitrary bearer token e.g. Authorization: Bearer not-a-real-token to read PFD application data via GET...

CVE-2026-43321

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability arises from the kernel's failure to correctly identify and mark active registers during indirect jump operations within the BPF program execution. An attacker could potentially exploit this to manipula...

CVE-2026-43306

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF crypto component. A local attacker, by running a specially crafted BPF program, could trigger a type mismatch in function pointers when Control Flow Integrity CFI is enabled. This can lead to a kernel internal error, resulting in a...

CVE-2026-43296

A flaw was found in the Linux kernel's octeontx2-af driver. This vulnerability arises from issues within the NIX SQ Send Queue manager's sticky mode and the PSE Packet Stream Engine, which can lead to system stalls, deadlocks, and credit drops. When multiple Send Queues share a Send Message Queue...
