CVE-2026-43254

CVE-2026-43254: Linux kernel openvpn TCP stream handling corrected. Ovpn_tcp_recv now allocates a separate skb per packet and uses skb_copy_bits to copy only the packet payload, skipping the 2-byte length prefix; length checks guard allocation to prevent invalid skbs. This resolves header offset ...

CVE-2026-43254

In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - fix packet extraction from stream When processing TCP stream data in ovpntcprecv, we receive large cloned skbs from strprcv that may contain multiple coalesced packets. The current implementation has two bugs: 1. Head...

In the Linux kernel, the following vulnerability has been resolved: media: iris: gen2: Add sanity check for session stop In iriskillsession, inst-state is set to IRISINSTERROR and sessionclose is executed, which will kfreeinsthfigen2-packet. If stopstreaming is called afterward, it will cause a...

CVE-2026-43070

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier fails to correctly reset a register's ID after a BPFEND byte swap operation. This oversight can lead to the verifier incorrectly propagating learned memory bounds to other registers, creating false confidence...

CVE-2026-43113

In the Linux kernel, the following vulnerability has been resolved: wifi: wl1251: validate packet IDs before indexing txframes wl1251txpacketcb uses the firmware completion ID directly to index the fixed 16-entry wl-txframes array. The ID is a raw u8 from the completion block, and the callback do...

CVE-2026-43113

In the Linux kernel, CVE-2026-43113 affects the wl1251 Wi‑Fi driver. The function wl1251_tx_packet_cb() uses the firmware completion ID (a raw u8) to index a fixed 16-entry wl->tx_frames[] array without validating that the ID fits. The callback can dereference out-of-range IDs. The fix rejects...
