CVE-2026-98033

The Linux kernel contains a vulnerability in its BPF subsystem where callback frame constructors incorrectly clear the map_uid field during initialization. Because map_uid is the unique identifier for inner maps sharing a template, clearing it allows different inner maps to appear identical. This...

CVE-2026-64353

CVE-2026-64353 is a Linux kernel BPF verifier flaw affecting ARRAY_OF_MAPS that use a BPF_F_INNER_MAP template. When a concrete inner array with a different max_entries replaces the template, the verifier's const-key lookup nullness elision incorrectly uses the template's max_entries instead of t...
