CVE-2026-45903

CVE-2026-45903 concerns the Linux kernel where the BPF verifier memory-access flag handling in helper prototypes was incorrect. After a verifier refactor, several helpers using ARG_PTR_TO_MEM lacked MEM_RDONLY or MEM_WRITE, causing the verifier to incorrectly assume buffers were unchanged across ...

CVE-2026-45886

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bpfxdpstorebytes proto for read-only arg While making some maps in Cilium read-only from the BPF side, we noticed that the bpfxdpstorebytes proto is incorrect. In particular, the verifier was throwing the following error...

CVE-2026-45859

The CVE-2026-45859 entry describes a Linux kernel netfilter nfnetlink_queue issue where a shared-unconfirmed nf_conn entry is not checked before segmentation, causing UDP packets to be dropped instead of queued when F_GSO is not set and a GSO packet arrives. The regression arose due to the check ...

CVE-2026-45844

Summary: CVE-2026-45844 affects the Linux kernel netfilter arp_tables on IEEE1394 (FireWire) interfaces. The vulnerability arises because arp_packet_match() unconditionally parses the ARP payload assuming both source and target hardware addresses exist, while IPv4-over-IEEE1394 ARP omits the targ...

CVE-2026-45843

CVE-2026-45843 affects the Linux kernel’s SLIP/VJ-compressed TCP header handling (slip and slhc_uncompress). The vulnerability stems from decode() and pull16() not enforcing bounds against the packet end, and decode() masking its return value to 0xFFFF, causing potential over-reads when a compres...
