BELL-CVE-2026-98233

Affected: Alpaquita:23: linux-lts, Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

fkie_cve-2026-98233

In the Linux kernel, the following vulnerability has been resolved:

net/packet: clear RX owner on VNET header error

Commit 61fad6816fc1 ("net/packet: tpacket_rcv: avoid a producer race condition") added rx_owner_map and made tpacket_rcv() claim a V1 or V2 ring slot before converting the virtio-net header. If the conversion fails, the drop path leaves the slot claimed.

With a one-frame TPACKET_V2 ring, an unsupported UDP GSO packet leaves the only slot unavailable, so the ring also drops the next valid packet.

Clear the ownership bit on this error path. TPACKET_V3 already clears its block state here.
