CVE-2026-98854 of/overlay: only treat a positive changeset id as registered

In the Linux kernel, the following vulnerability has been resolved: of/overlay: only treat a positive changeset id as registered ofoverlayfdtapply stores the idralloc return value in ovcs-id before checking it. On failure the stored id is negative, freeoverlaychangeset's "if ovcs-id" check passes...

CVE-2026-98852

The Linux kernel contained a vulnerability regarding the detection of IPv6 extension headers in tunneled packets during checksum offload. Specifically, the skb_gso_has_extension_hdr() function failed to correctly handle various paths, leading to scenarios where GSO packets were incorrectly droppe...

CVE-2026-98850

The Linux kernel contains a vulnerability in net/packet where the tpacket_snd() function fails to bound the len_sum variable. Because userspace can recycle completed frames concurrently, len_sum can wrap into a negative range after sufficient transmissions. Specifically, certain frame sizes can p...

CVE-2026-98851

The Linux kernel contains a vulnerability in netfilter: nft_flow_offload where nft_flow_offload_init() incorrectly handles reference counting. The function increments the flowtable use count using nft_use_inc() but fails to decrement it if the subsequent nf_ct_netns_get() call fails. Because uppe...
