{"id":"DEBIAN-CVE-2022-49406","details":"In the Linux kernel, the following vulnerability has been resolved:  block: Fix potential deadlock in blk_ia_range_sysfs_show()  When being read, a sysfs attribute is already protected against removal with the kobject node active reference counter. As a result, in blk_ia_range_sysfs_show(), there is no need to take the queue sysfs lock when reading the value of a range attribute. Using the queue sysfs lock in this function creates a potential deadlock situation with the disk removal, something that a lockdep signals with a splat when the device is removed:  [  760.703551]  Possible unsafe locking scenario: [  760.703551] [  760.703554]        CPU0                    CPU1 [  760.703556]        ----                    ---- [  760.703558]   lock(&q-\u003esysfs_lock); [  760.703565]                                lock(kn-\u003eactive#385); [  760.703573]                                lock(&q-\u003esysfs_lock); [  760.703579]   lock(kn-\u003eactive#385); [  760.703587] [  760.703587]  *** DEADLOCK ***  Solve this by removing the mutex_lock()/mutex_unlock() calls from blk_ia_range_sysfs_show().","modified":"2026-08-27T23:04:18.072699918Z","published":"2025-02-26T07:01:17.123Z","upstream":["CVE-2022-49406"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49406"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49406.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49406.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49406.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"}]}
