CVE-2026-98233

net/packet: clear RX owner on VNET header error

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.
