Logic\nin napi_poll context would cause an out-of-bound read by first increment\nthe pointer address by byte address space and then dereference the value.\nRather, the intended logic was to dereference first and then increment the\nunderlying value.","modified":"2026-03-20T12:32:40.267929Z","published":"2024-03-26T17:49:59.220Z","related":["ALSA-2024:4349","ALSA-2024:4352","USN-6818-2","USN-6819-2"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52626.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/33cdeae8c6fb58cc445f859b67c014dc9f60b4e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3876638b2c7ebb2c9d181de1191db0de8cac143a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/40e0d0746390c5b0c31144f4f1688d72f3f8d790"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52626.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52626"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e5d30f7da35720060299483e65fc372980a82dfb"},{"fixed":"40e0d0746390c5b0c31144f4f1688d72f3f8d790"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"92214be5979c0961a471b7eaaaeacab41bdf456c"},{"fixed":"33cdeae8c6fb58cc445f859b67c014dc9f60b4e0"},{"fixed":"3876638b2c7ebb2c9d181de1191db0de8cac143a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"42b11d1293e5a0f932c0b6e891b2c7bae57b839d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52626.json"}}],"schema_version":"1.7.5"}
