This leaves a dangling handler that may be called when\nthe parent interrupt fires after the driver has been removed, potentially\naccessing freed memory and causing a kernel crash.\n\nAdditionally, the parent_irq obtained via irq_of_parse_and_map() is not\nstored, making it inaccessible in the remove function. Moreover, interrupt\nmappings created during probe are not properly disposed.\n\nFix this by:\n\n   - Saving parent_irq in probe\n   - Clearing the chained handler with NULL in ts4800_ic_remove()\n   - Disposing all IRQ mappings before domain removal to prevent resource\n     leaks","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3f31f49afffa169cd01e6c37568c4df3eb1051af","https://git.kernel.org/stable/c/4e8d498d32b6c67d73bb8b317ff316ff37897a3e","https://git.kernel.org/stable/c/98bf7e54cec07d514b3575c11896a8b12d50ecc4","https://git.kernel.org/stable/c/9ed0dca2aa05908b33ecf0bb15c7953947529542","https://git.kernel.org/stable/c/b5b2b2cb6a91908e6c23958c9ce6d5ba2fdb686c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72384","score":0.00215,"percentile":0.11852,"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).
