Overview
CVE-2026-72402 is a known-severity vulnerability. It was published on August 15, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Mask pseudo pointer values in verifier logs
print_bpf_insn() masks ldimm64 immediates for pointer-bearing pseudo
sources when pointer leaks are not allowed, but the mask only covers
BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE.
BPF_PSEUDO_MAP_IDX, BPF_PSEUDO_MAP_IDX_VALUE, and BPF_PSEUDO_BTF_ID can
also be resolved to kernel pointer values before the verifier log prints
the instruction. Include them in the existing pointer classification so
the log prints 0x0 instead of the rewritten address.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-72402?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-72402 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
