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)","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2004f45ef83f07f43f5da6ede780b08068c7583d"},{"fixed":"9540b0a4d13e4ede64ae1197d66a176d2149daa9"},{"fixed":"31180638a33acad12c863132704a76536fb66211"},{"fixed":"b15825deac1acff72638bbc8f05b89ceef8dfb13"},{"fixed":"201151e120f0062bcda21cad5d007b82725ad23b"},{"fixed":"a914aa802669e073f014dae2e5708633b5cecd34"},{"fixed":"e09689286385a66311ac6922af95339d7a3cef8d"},{"fixed":"de988c7a31f0774f07894cfe4802996f318e2870"},{"fixed":"da48bc4461b8a5ebfb9264c9b191a701d8e99009"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53329.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"5.10.260"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.94"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53329.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/201151e120f0062bcda21cad5d007b82725ad23b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/31180638a33acad12c863132704a76536fb66211"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9540b0a4d13e4ede64ae1197d66a176d2149daa9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a914aa802669e073f014dae2e5708633b5cecd34"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b15825deac1acff72638bbc8f05b89ceef8dfb13"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da48bc4461b8a5ebfb9264c9b191a701d8e99009"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de988c7a31f0774f07894cfe4802996f318e2870"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e09689286385a66311ac6922af95339d7a3cef8d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53329.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53329"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53329.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
