Also we have some dependent\nloads and stores for which we need the correct ordering, and we lack the\nneeded barriers. Fix this by grabbing the ct->lock after the wait, which\nis also held by the completion side.\n\nv2 (Badal):\n - Also print done after acquiring the lock and seeing timeout.\n\n(cherry picked from commit 52789ce35c55ccd30c4b67b9cc5b2af55e0122ea)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/8ed7dd4c55e4fb21531a9645aeb66a30eaf43a46","https://git.kernel.org/stable/c/db7f92af626178ba59dbbcdd5dee9ec24a987a88"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:56:33.105311382+00:00"},"epss":{"cve":"CVE-2024-50030","score":0.00229,"percentile":0.13738,"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).
