In the Linux kernel, the following vulnerability has been resolved: gve: DQO: reject TSO packets with an out of range MSS gvepreptso notes that the device requires the MSS to be len and gsosegs, never gsosize. Such a packet reaches gvetxfilltsoctxdesc, which puts gsosize into the mss field of the...

CVE-2026-98556

The Linux kernel contains a vulnerability in the gve driver where TSO (TCP Segmentation Offload) packets with an out-of-range MSS (Maximum Segment Size) are not properly rejected. The gve_prep_tso() function fails to enforce the required limit of

CVE-2026-98555

A vulnerability exists in the Linux kernel 's LLC (Light Link Control) component. Specifically, when the llc_mac_hdr_init() function fails within llc_conn_ac_resend_i_xxx_x_set_0_or_send_rr() , the system calls kfree_skb(skb) instead of kfree_skb(nskb) . This oversight causes a memory leak of the...

CVE-2026-98554

The Linux kernel contains a vulnerability in the vlan component where certain callers (e.g., llc_alloc_frame() ) or skbs allocated before dynamic headroom changes can reach vlan_dev_hard_header() with insufficient headroom. This condition triggers a skb_under_panic() . The issue is addressed by u...
