AZL-99629 CVE-2026-80905 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: net: tap: fix wrong transportheader when sending VLAN-tagged frame In tapgetuserxdp, when processing a VLAN-tagged frame e.g. ETHP8021Q, skbsetnetworkheader is called first to advance networkheader past the VLAN tag to the inner...

CVE-2026-80905

Linux kernel tap driver vulnerability in tap_get_user_xdp(). When processing VLAN-tagged frames (e.g., ETH_P_8021Q), skb_set_network_header() was called before skb_probe_transport_header(), causing the flow dissector to misinterpret the inner protocol header (e.g., an IP header) as a VLAN header....

CVE-2026-46321

A flaw was found in the Linux kernel. A local attacker with access to the tun/tap device can exploit this vulnerability. By sending network frames shorter than the expected header length, the system fails to free allocated memory pages, leading to memory leaks. This can exhaust system memory,...

CVE-2026-46207

A flaw was found in the Linux kernel's vsock/virtio component. When processing non-linear data buffers for the vsockmon tap device, the system did not correctly initialize the payload. This oversight could lead to uninitialized data being copied to the monitoring interface, potentially resulting ...

Fuzzing µC/OS protocol stacks, Part 3: TCP/IP server fuzzing, implementing a TAP driver

This is the final post in the three-part series that details techniques I used to fuzz two µC/OS protocol stacks: µC/TCP-IP and µC/HTTP-server. The first post highlighted code modifications necessary for developing a fuzzing harness tailored for the µC/HTTP-server. The second discussed a techniqu...
