CVE-2026-64207

A flaw was found in the Linux kernel's DualPI2 Dual-rate PI2 queue discipline. This vulnerability arises from incorrect accounting of Generic Segmentation Offload GSO backlog, where the parent queue such as QFQ - Hierarchical Fair Queueing miscalculates the number of queued packets. This...

SUSE CVE-2026-53091

In the Linux kernel, the following vulnerability has been resolved: net: pull headers in qdiscpktlensegsinit Most ndostartxmit methods expects headers of gso packets to be already in skb-head. net/core/tso.c users are particularly at risk, because tsobuildhdr does a memcpyhdr, skb-data, hdrlen;...

CVE-2026-53228

The CVE-2026-53228 entry documents a vulnerability in the Linux kernel SIT IPv6 tunnel driver. When GSO offloads are used, the code may keep a stale pointer to the inner IPv6 header after skb header unclone and potential headroom reallocation, leading to reads from freed memory. A fix reloads the...

CVE-2026-53091

The CVE-2026-53091 issue concerns the Linux kernel’s handling of GSO packet headers during qdisc_pkt_len_segs_init(). The root cause is that many ndo_start_xmit() paths assume headers are already in skb->head, while tso_build_hdr() may copy from skb->data, and qdisc_pkt_len_segs_init() diss...
