That means it\nnever frees the correct index and keeps the crossbar register connection\nto the source interrupt active.\n\nIf it would not reset the domain data, then this would be even worse as\nirq_data->hwirq holds the source interrupt number, but both the map and\nregister index need the corresponding GIC SPI number and not the source\ninterrupt number. This might even result in an out of bounds access as\nthe source interrupt number can be higher than the maximal index space.\n\nFix this by using the GIC SPI index from the parent domain's irq_data.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/043db005a8d6932dc7d217c86307e9af0bc10ddc","https://git.kernel.org/stable/c/13bdb5140405ff283f9052e65ee1d5c2303765c7","https://git.kernel.org/stable/c/1c48dc6a0c1ef47a9fa24611e60bc2f4ee4dd0df","https://git.kernel.org/stable/c/36ca587f55a2c04468a89fd16174bb2f78dc04ec","https://git.kernel.org/stable/c/424130169dc03b84ea604685409726d61bcec859"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72153","score":0.0022,"percentile":0.12513,"date":"2026-10-31"},"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).
