From Debugging to Code Execution: RCE in Microsoft DevLabs’ DebugMCP?

Introduction AI-assisted development has crossed a threshold. The question is no longer whether your IDE communicates with an AI, it's how deeply that AI is now wired into your local environment. The Model Context Protocol MCP is one of the plumbing behind this shift: a JSON-RPC-based protocol th...

AZL-104603 CVE-2026-98046 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: bpf: Mark bpfbtffindbynamekind as sleepable When bpfbtffindbynamekind finds a type in module BTF, it returns a new BTF object fd through btfnewfd. This reaches anoninodegetfd, which can sleep while allocating or expanding the...

CVE-2026-98046

The Linux kernel contains a vulnerability where the bpf_btf_find_by_name_kind() helper is incorrectly treated as non-sleepable. Because the helper does not set might_sleep , the BPF verifier allows its use in non-sleepable contexts like BPF timer callbacks . This can lead to a condition where ano...

CVE-2026-98035

The Linux kernel contains a vulnerability in the BPF subsystem where rhtab_map_update_existing() and rhtab_delete_elem() incorrectly call bpf_obj_free_fields() during map operations. This is problematic because these operations can execute in an NMI context , where releasing complex fields like k...

CVE-2026-97971

The Linux kernel is vulnerable to a race condition where legitimize_ns() takes a reference on a candidate namespace before may_list_ns() determines if the caller has permission to see it.
