CVE-2026-98033 bpf: Preserve inner map identity in callback frames

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve inner map identity in callback frames Callback frame constructors initialize map-typed argument registers with markregknownzero and then restore mapptr. This clears mapuid, which is the only field distinguishing inn...

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...
