UBUNTU-CVE-2026-72402: Medium severity ubuntu/linux-hwe-edge vulnerability

Published Aug 15, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: bpf: Mask pseudo pointer values in verifier logs printbpfinsn() masks ldimm64 immediates for pointer-bearing pseudo sources when pointer leaks are not allowed, but the mask only covers BPFPSEUDOMAPFD and BPFPSEUDOMAPVALUE. BPFPSEUDOMAPIDX, BPFPSEUDOMAPIDXVALUE, and BPFPSEUDOBTFID 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.

    Linux kernel BPF verifier logs pointer classification in print_bpf_insn() = Include BPF_PSEUDO_MAP_IDX, BPF_PSEUDO_MAP_IDX_VALUE, and BPF_PSEUDO_BTF_ID

Frequently Asked Questions

1

Who can exploit this issue?

An attacker needs local access and low privileges sufficient to load or submit BPF programs that cause verifier logging. The vulnerability concerns kernel pointer values exposed through those verifier logs.

2

What information could be disclosed?

Verifier logs may print rewritten kernel pointer addresses for ldimm64 instructions using BPF_PSEUDO_MAP_IDX, BPF_PSEUDO_MAP_IDX_VALUE, or BPF_PSEUDO_BTF_ID pseudo sources. The resolved behavior masks these values as 0x0 when pointer leaks are not allowed.

3

Are all listed Ubuntu kernel variants potentially relevant?

The affected software list includes Ubuntu linux, linux-realtime, linux-azure, linux-gcp, linux-azure-fde, linux-gke, linux-riscv, and linux-gkeop packages. The provided data does not identify specific fixed or affected package versions.
