{"id":"DEBIAN-CVE-2022-49944","details":"In the Linux kernel, the following vulnerability has been resolved:  Revert \"usb: typec: ucsi: add a common function ucsi_unregister_connectors()\"  The recent commit 87d0e2f41b8c (\"usb: typec: ucsi: add a common function ucsi_unregister_connectors()\") introduced a regression that caused NULL dereference at reading the power supply sysfs.  It's a stale sysfs entry that should have been removed but remains with NULL ops.  The commit changed the error handling to skip the entries after a NULL con-\u003ewq, and this leaves the power device unreleased.  For addressing the regression, the straight revert is applied here. Further code improvements can be done from the scratch again.","modified":"2026-08-27T23:04:24.109337318Z","published":"2025-06-18T11:15:21.377Z","upstream":["CVE-2022-49944"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49944"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.2-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49944.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.2-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49944.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.2-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49944.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"}]}
