Fix\nthis by:\n\nFirstly, make rxrpc_destroy_all_calls() only dump the first ten calls that\nare unexpectedly still on the list.  Limiting the number of steps means\nthere's no need to call cond_resched() or to remove calls from the list\nhere, thereby eliminating the need for rxrpc_put_call() to check for that.\n\nrxrpc_put_call() can then be fixed to unconditionally delete the call from\nthe list as it is the only place that the deletion occurs.","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-835"],"references":["https://git.kernel.org/stable/c/146d4ab94cf129ee06cd467cb5c71368a6b5bad6","https://git.kernel.org/stable/c/280efb85e9759881a9d31d0874baa04583cb6c09","https://git.kernel.org/stable/c/3be718f659683ad89fad6f1eb66bee99727cae64","https://git.kernel.org/stable/c/3e47a38e584b905359fe0ce5be5165d1e8592a90","https://git.kernel.org/stable/c/93fc15be44a35b8e3c58d0238ac0d9b7c53465ff"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-31642","score":0.00129,"percentile":0.02473,"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).
