CVE-2026-43254

CVE-2026-43254: Linux kernel openvpn TCP stream handling corrected. Ovpn_tcp_recv now allocates a separate skb per packet and uses skb_copy_bits to copy only the packet payload, skipping the 2-byte length prefix; length checks guard allocation to prevent invalid skbs. This resolves header offset ...

CVE-2026-43276

Summary: CVE-2026-43276 is a Linux kernel issue in the mana network driver causing a use-after-free during PCI service rescan. The crash occurs when mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup() frees gc->service_wq, and a subsequent resume path leads to a second removal via man...

CVE-2026-43315

CVE-2026-43315 involves the Linux kernel KVM nSVM warning path.
