CVE-2026-98278

The Linux kernel contains a logic issue where dev_fill_forward_path() triggers a WARN_ON_ONCE warning when a flowtable attempts to offload a flow through a tunnel that resolves back to itself. This routing loop can be configured by any user with CAP_NET_ADMIN privileges. Because ip_tunnel_xmit() ...

CVE-2026-98277

The Linux kernel contains a vulnerability in the fbnic driver where the fbnic_tx_map() function fails to ring the doorbell or issue a completion request for packets in a burst if the final packet in that burst is dropped (e.g., due to skb_put_padto(), skb_cow_head(), or a DMA mapping failure). Th...

CVE-2026-98276

The Linux kernel is vulnerable to a UDP socket use-after-free due to a race condition in sock_gettstamp(). The sk->sk_flags field is modified using non-atomic operations without holding the socket lock, specifically when sock_enable_timestamp() sets the SOCK_TIMESTAMP bit. This allows a SIOCGS...

CVE-2026-98275

The Linux kernel contains a vulnerability in the cortina ethernet driver regarding how it handles the RX overrun interrupt . The gmac_irq() function incorrectly acknowledges the interrupt using the RX descriptor error bit from status register 0, instead of the bit reported in status register 4. F...
