{"id":"DEBIAN-CVE-2022-49711","details":"In the Linux kernel, the following vulnerability has been resolved:  bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()  In fsl_mc_bus_remove(), mc-\u003eroot_mc_bus_dev-\u003emc_io is passed to fsl_destroy_mc_io(). However, mc-\u003eroot_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc-\u003eroot_mc_bus_dev-\u003emc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc-\u003eroot_mc_bus_dev-\u003emc_io in a local variable and pass to fsl_destroy_mc_io().  This patch needs rework to apply to kernels older than v5.15.","modified":"2026-09-01T16:05:33.266880522Z","published":"2025-02-26T07:01:46.893Z","upstream":["CVE-2022-49711"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49711"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49711.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49711.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49711.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"}]}
