{"id":"DEBIAN-CVE-2024-26933","details":"In the Linux kernel, the following vulnerability has been resolved:  USB: core: Fix deadlock in port \"disable\" sysfs attribute  The show and store callback routines for the \"disable\" sysfs attribute file in port.c acquire the device lock for the port's parent hub device.  This can cause problems if another process has locked the hub to remove it or change its configuration:  \tRemoving the hub or changing its configuration requires the \thub interface to be removed, which requires the port device \tto be removed, and device_del() waits until all outstanding \tsysfs attribute callbacks for the ports have returned.  The \tlock can't be released until then.  \tBut the disable_show() or disable_store() routine can't return \tuntil after it has acquired the lock.  The resulting deadlock can be avoided by calling sysfs_break_active_protection().  This will cause the sysfs core not to wait for the attribute's callback routine to return, allowing the removal to proceed.  The disadvantage is that after making this call, there is no guarantee that the hub structure won't be deallocated at any moment.  To prevent this, we have to acquire a reference to it first by calling hub_get().","modified":"2026-09-15T09:03:05.890850414Z","published":"2024-05-01T06:15:07.930Z","upstream":["CVE-2024-26933"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-26933"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.85-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1","6.1.55-1~bpo11+1","6.1.64-1","6.1.66-1","6.1.67-1","6.1.69-1","6.1.69-1~bpo11+1","6.1.76-1","6.1.76-1~bpo11+1","6.1.82-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26933.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.7.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26933.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.7.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26933.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:H/I:H/A:H"}]}
