However, the work structures\n(zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by\nthese handlers were allocated and initialized after the registration\ncall.\n\nThis created a race window where, if the firmware triggered an event\nimmediately after registration but before allocation, the callback\n(suspend_event_callback or subsystem_restart_event_callback) would\ndereference a NULL pointer in work_pending(), leading to a crash.\n\nFix this by allocating and initializing the work structures before\nregistering the events.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/07ea9081b8fefb99e2f427e0f0602a5e576cb120","https://git.kernel.org/stable/c/d349aa118ff5e4cab88424ce1b16e08edd70f8bb","https://git.kernel.org/stable/c/e124f7b170337563d78a7a6aa152c897d229bc39","https://git.kernel.org/stable/c/fb445935338405110baca8f541a2df3b4cb8d712"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-80655","score":0.00209,"percentile":0.10949,"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).
