In the\nperformance test scenario, function irq_wait_for_interrupt() will always\nreturn 0 if lots of interrupts occurs and the CPU will be continuously\nconsumed. As a result, the CPU cannot run the watchdog thread. When the\nwatchdog time exceeds the specified time, call trace occurs.\n\nTo fix it, add cond_resched() to execute the watchdog thread.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/2174bbc235f79fce88ea71fd08cf836568fcad5f","https://git.kernel.org/stable/c/2233c4a0b948211743659b24c13d6bd059fa75fc","https://git.kernel.org/stable/c/2991a023896b79e6753813ed88fbc98979713c73","https://git.kernel.org/stable/c/3dd2c5cb2c698a02a4ed2ea0acb7c9909374a8bf","https://git.kernel.org/stable/c/50ddf4b0e1a4cb5e9ca0aac3d0a73202b903c87f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2024-56589","score":0.00236,"percentile":0.14609,"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).
