{"id":"DEBIAN-CVE-2023-53664","details":"In the Linux kernel, the following vulnerability has been resolved:  OPP: Fix potential null ptr dereference in dev_pm_opp_get_required_pstate()  \"opp\" pointer is dereferenced before the IS_ERR_OR_NULL() check. Fix it by removing the dereference to cache opp_table and dereference it directly where opp_table is used.  This fixes the following smatch warning:  drivers/opp/core.c:232 dev_pm_opp_get_required_pstate() warn: variable dereferenced before IS_ERR check 'opp' (see line 230)","modified":"2026-09-15T09:02:51.871988113Z","published":"2025-10-07T16:15:50.163Z","upstream":["CVE-2023-53664"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-53664"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53664.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53664.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
