{"id":"DEBIAN-CVE-2024-58084","details":"In the Linux kernel, the following vulnerability has been resolved:  firmware: qcom: scm: Fix missing read barrier in qcom_scm_get_tzmem_pool()  Commit 2e4955167ec5 (\"firmware: qcom: scm: Fix __scm and waitq completion variable initialization\") introduced a write barrier in probe function to store global '__scm' variable.  We all known barriers are paired (see memory-barriers.txt: \"Note that write barriers should normally be paired with read or address-dependency barriers\"), therefore accessing it from concurrent contexts requires read barrier.  Previous commit added such barrier in qcom_scm_is_available(), so let's use that directly.  Lack of this read barrier can result in fetching stale '__scm' variable value, NULL, and dereferencing it.  Note that barrier in qcom_scm_is_available() satisfies here the control dependency.","modified":"2026-09-15T09:03:00.525288124Z","published":"2025-03-06T17:15:21.890Z","upstream":["CVE-2024-58084"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-58084"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.15-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-58084.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.15-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-58084.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"}]}
