CVE-2026-98279

The Linux kernel contains a vulnerability in the btrfs filesystem where a lack of space or a qgroup limit during the cleanup of verity items can cause the entire filesystem to be forced into read-only mode. This occurs because rollback_verity() requires its own metadata reservation; if denied, th...

CVE-2026-98279 btrfs: handle lack of space when cleaning up verity items

In the Linux kernel, the following vulnerability has been resolved: btrfs: handle lack of space when cleaning up verity items When enableverity hits the qgroup limit, rollbackverity needs its own metadata reservation. When the qgroup limit or lack of space refuses the rollback, the whole filesyst...

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...
