This made the comparison\nresult invalid when the immediate operand was negative. Note that $at\nis mapped to BPF_REG_AX, which is used for constant blinding.\n\nFix the instruction to use the immediate form.\n\nFound with test_bpf on MIPS32r1 emulated by QEMU.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1547e9f3a7d71971216e6dba30270cae13fe4e02","https://git.kernel.org/stable/c/1bd91670966a7142ac94f2cebe2b5ae6bf5cb0c8","https://git.kernel.org/stable/c/6f939529ed6c580e9b6c5daa20be67fa0b3d4cf0","https://git.kernel.org/stable/c/876ef04c75c2751acfd355606fca3eced71dec65","https://git.kernel.org/stable/c/beeae92e70e705e90a0d6d9b3b8498ee3b92f495"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98572","score":0.00211,"percentile":0.11294,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
