If a resize fails after some buffers were enlarged, a retry\nrevisits those enlarged buffers.\n\nRetrying the same size then returns -ENOMEM because alloc_pages_bulk()\nhas no pages to add and the unchanged return value is treated as a\nfailure. Retrying an intermediate size allocates a temporary pointer\narray smaller than gbuf->nrpages and copies more existing pointers than\nthe array can hold.\n\nSkip buffers that already satisfy the request. Once all remaining\nbuffers have caught up, advancing z_erofs_gbuf_nrpages again describes\nthe guaranteed minimum size across the pool.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/3fbdd15d5830f52661eb78be95058d101cb0c2cb","https://git.kernel.org/stable/c/7267557ce98ccd07faaf3bc86382448950cc4ff6","https://git.kernel.org/stable/c/7f4a89d4f0d6acaf4b756c31de48f2109a257b70","https://git.kernel.org/stable/c/a7d097cf01301c5da37927c8f26123d006f0fd8a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89602","score":0.00176,"percentile":0.07077,"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).
