CVE-2026-31401

A flaw was found in the Linux kernel's Human Interface Device HID BPF Berkeley Packet Filter component. This vulnerability occurs in the hidhwrequest function, where an uncontrolled return value from dispatchhidbpfrawrequests can lead to a buffer overflow. This could allow a local attacker to cau...

CVE-2026-23412

A flaw was found in the Linux kernel's netfilter BPF Berkeley Packet Filter component. A local attacker could exploit this by initiating a concurrent process to dump hooks via nfnetlinkhooks, which triggers a use-after-free vulnerability. This could lead to system instability or a denial of servi...

New Whitepaper: Stealthy BPFDoor Variants are a Needle That Looks Like Hay

Executive Overview Advanced persistent threats APTs are constantly and consistently changing tactics as network defenders plug holes in defenses. Static indicators of compromise IoCs for the BPFDoor have been widely deployed, forcing threat actors to get creative in their use of this particular...
