In the Linux kernel, the following vulnerability has been resolved: net: add pskbmaypull to skbgroreceivelist skbgroreceivelist calls skbpullskb, skbgrooffsetskb without first ensuring the data is in the linear area via pskbmaypull. When the skb arrives via napigrofrags, skbheadlen can be 0 all...

CVE-2026-53226

The CVE-2026-53226 issue affects the Linux kernel GPIO Rockchip driver: generic IRQ chips allocated via irq_alloc_domain_generic_chips() are not freed on driver removal, leaving domain generic chips and the global gc_list leaked and potentially visited later by suspend/resume/shutdown callbacks, ...

CVE-2026-53224

The vulnerability CVE-2026-53224 affects the Linux kernel SCTP implementation. The issue arises from insufficient validation of embedded INIT chunks and address list lengths in cookies: sctp_unpack_cookie() may accept a truncated INIT chunk, and the subsequent sctp_process_init() could read INIT ...

CVE-2026-53212

The CVE-2026-53212 issue affects the Linux kernel nft_tunnel implementation within netfilter, where nft_tunnel_obj_destroy() used metadata_dst_free() to free a metadata_dst, bypassing dst_entry refcount accounting. This could leave in-flight packets that hold references (via dst_hold()) dangling,...
