This would cause krealloc to\nreturn a smaller buffer than expected, leading to heap overflows on\nsubsequent vector appends.\n\nReplace krealloc() with krealloc_array() which performs an internal\noverflow check and returns NULL on wrap, preventing the issue.\n\n(cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-674","CWE-190"],"references":["https://git.kernel.org/stable/c/201151e120f0062bcda21cad5d007b82725ad23b","https://git.kernel.org/stable/c/31180638a33acad12c863132704a76536fb66211","https://git.kernel.org/stable/c/9540b0a4d13e4ede64ae1197d66a176d2149daa9","https://git.kernel.org/stable/c/a914aa802669e073f014dae2e5708633b5cecd34","https://git.kernel.org/stable/c/b15825deac1acff72638bbc8f05b89ceef8dfb13"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-53329","score":0.00147,"percentile":0.03893,"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).
