{"id":"UBUNTU-CVE-2025-12105","details":"A flaw was found in the asynchronous message queue handling of the libsoup library, widely used by GNOME and WebKit-based applications to manage HTTP/2 communications. When network operations are aborted at specific timing intervals, an internal message queue item may be freed twice due to missing state synchronization. This leads to a use-after-free memory access, potentially crashing the affected application. Attackers could exploit this behavior remotely by triggering specific HTTP/2 read and cancel sequences, resulting in a denial-of-service condition.","modified":"2026-04-22T18:57:35.154276Z","published":"2025-10-23T10:15:00Z","related":["USN-7932-1"],"upstream":["CVE-2025-12105"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-12105"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-12105"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-12105"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2405992"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7932-1"}],"affected":[{"package":{"name":"libsoup3","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/libsoup3@3.0.7-0ubuntu1+esm6?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.7-0ubuntu1+esm6"}]}],"versions":["3.0.4-2","3.0.4-3","3.0.5-1","3.0.7-0ubuntu1","3.0.7-0ubuntu1+esm1","3.0.7-0ubuntu1+esm2","3.0.7-0ubuntu1+esm3","3.0.7-0ubuntu1+esm4","3.0.7-0ubuntu1+esm5"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"gir1.2-soup-3.0","binary_version":"3.0.7-0ubuntu1+esm6"},{"binary_name":"libsoup-3.0-0","binary_version":"3.0.7-0ubuntu1+esm6"},{"binary_name":"libsoup-3.0-common","binary_version":"3.0.7-0ubuntu1+esm6"},{"binary_name":"libsoup-3.0-tests","binary_version":"3.0.7-0ubuntu1+esm6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-12105.json"}},{"package":{"name":"libsoup3","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libsoup3@3.4.4-5ubuntu0.6?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.4-5ubuntu0.6"}]}],"versions":["3.4.2-4","3.4.4-1","3.4.4-2","3.4.4-4","3.4.4-5","3.4.4-5build1","3.4.4-5build2","3.4.4-5ubuntu0.1","3.4.4-5ubuntu0.2","3.4.4-5ubuntu0.3","3.4.4-5ubuntu0.4","3.4.4-5ubuntu0.5"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"3.4.4-5ubuntu0.6","binary_name":"gir1.2-soup-3.0"},{"binary_name":"libsoup-3.0-0","binary_version":"3.4.4-5ubuntu0.6"},{"binary_name":"libsoup-3.0-common","binary_version":"3.4.4-5ubuntu0.6"},{"binary_name":"libsoup-3.0-tests","binary_version":"3.4.4-5ubuntu0.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-12105.json"}},{"package":{"name":"libsoup3","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libsoup3@3.6.5-4ubuntu0.1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.6.5-4ubuntu0.1"}]}],"versions":["3.6.5-1","3.6.5-1ubuntu1","3.6.5-3","3.6.5-4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gir1.2-soup-3.0","binary_version":"3.6.5-4ubuntu0.1"},{"binary_name":"libsoup-3.0-0","binary_version":"3.6.5-4ubuntu0.1"},{"binary_name":"libsoup-3.0-common","binary_version":"3.6.5-4ubuntu0.1"},{"binary_name":"libsoup-3.0-tests","binary_version":"3.6.5-4ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-12105.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
