However, now that we do the alloc & init before the attach, we can\nnow combine this as one unit and have the init do the alloc for us. This\nshould make the retry safe.\n\nReported by Sashiko.\n\nv2: Fix up the error unwind (CI)\n\n(cherry picked from commit 479669418253e0f27f8cf5db01a731352ea592e7)","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","CWE-825"],"references":["https://git.kernel.org/stable/c/155a372a1cc50fa93387c5d3cdfd614a61e1afd1","https://git.kernel.org/stable/c/39fdac6be02eb7c3460518c1c4085f75f935c4ce","https://git.kernel.org/stable/c/827062952ed9bdf4220466c1f05ce452d04bdedf","https://access.redhat.com/errata/RHSA-2026:42919","https://access.redhat.com/errata/RHSA-2026:45192"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-52950","score":0.00178,"percentile":0.07299,"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).
