CVE-2026-43099

The CVE-2026-43099 issue affects the Linux kernel, specifically the IPv4/ICMP path and the IPv6 stub handling. When the IPv6 stack is not active (CONFIG_IPV6=m and not loaded), ipv6_dev_find() may return ERR_PTR(-EAFNOSUPPORT); passing that to dev_hold() can cause a null pointer dereference and a...

CVE-2026-43098

Summary (concrete details from provided documents): CVE-2026-43098 affects the Linux kernel NFC subsystem, specifically the s3fwrn5 driver, where s3fwrn82_uart_read() may consume bytes into recv_skb and deliver a complete frame before a new receive buffer is allocated. If alloc_skb() fails, the c...

CVE-2026-43094

CVE-2026-43094 affects the Linux kernel ixgbevf driver on Hyper-V VMs. The root cause is a missing negotiate_features callback in the Hyper-V mac_ops table, causing ixgbevf_negotiate_api() to dereference a NULL hw->mac.ops.negotiate_features() during feature negotiation. This can lead to a NUL...
