Executing the argument function synchronously from within\ndpm_async_fn() may also be problematic for ordering reasons (it may\ncause a consumer device's resume callback to be invoked before a\nrequisite supplier device's one, for example).\n\nAddress this by changing the code in question to use\nasync_schedule_dev_nocall() for scheduling the asynchronous\nexecution of device suspend and resume functions and to directly\nrun them synchronously if async_schedule_dev_nocall() returns false.","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":["CWE-667"],"references":["https://git.kernel.org/stable/c/7839d0078e0d5e6cc2fa0b0dfbee71de74f1e557","https://git.kernel.org/stable/c/9bd3dce27b01c51295b60e1433e1dadfb16649f7","https://git.kernel.org/stable/c/a1d62c775b07213c73f81ae842424c74dd14b5f0","https://git.kernel.org/stable/c/e1c9d32c98309ae764893a481552d3f99d46cb34","https://git.kernel.org/stable/c/e681e29d1f59a04ef773296e4bebb17b1b79f8fe"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2023-52498","score":0.00238,"percentile":0.14906,"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).
