DEBIAN-CVE-2026-98061

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject tail calls directly from callback frames A tail call from a non-zero frame is modeled as a return from that frame. The verifier makes R0 unknown and calls preparefuncexit for the taken branch. When the current frame i...

CVE-2026-98033

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...

PT-2026-98696

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF subsystem where callback frame constructors initialize map-typed argument registers using mark reg known zero before restoring map ptr. This process clears the...
