Note that sock_release() is synchronous\nbut fput() usually delays the final close and clean-up.\n\nThe delay is not consequential in the other cases that were changed\nbut handshake_req_destroy_test1 is testing that handshake_req_cancel()\nfollowed by closing the file actually does call the ->hp_destroy\nmethod. Thus the PTR_EQ test at the end has to be sure that the\nfinal close is complete before it checks the pointer.\n\nWe cannot use a completion here because if ->hp_destroy is never\ncalled (ie, there is an API bug) then the test will hang.\n\nReported by: Guenter Roeck <linux@roeck-us.net>","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-401"],"references":["https://git.kernel.org/stable/c/4e1d71cabb19ec2586827adfc60d68689c68c194","https://git.kernel.org/stable/c/7f97805b8df6e33850e225e6bd3ebd9e246920af","https://git.kernel.org/stable/c/d74226e03df1bf19848f18344401f254345af912","https://git.kernel.org/stable/c/4e1d71cabb19ec2586827adfc60d68689c68c194","https://git.kernel.org/stable/c/7f97805b8df6e33850e225e6bd3ebd9e246920af"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:48:32.179249784+00:00"},"epss":{"cve":"CVE-2024-26831","score":0.00225,"percentile":0.13227,"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).
