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."}],"affected":[{"vendor":"GNOME","product":"libsoup","versions":[{"status":"affected","version":"0","versionType":"semver","lessThanOrEqual":"3.6.5"}],"packageName":"libsoup","collectionURL":"https://gitlab.gnome.org/GNOME/libsoup","defaultStatus":"unaffected"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup3","defaultStatus":"affected","versions":[{"version":"0:3.6.5-3.el10_1.7","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux:10.1"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10.0 Extended Update Support","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup3","defaultStatus":"affected","versions":[{"version":"0:3.6.5-3.el10_0.10","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux_eus:10.0"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup","defaultStatus":"unknown","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"libsoup","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2025:23139","name":"RHSA-2025:23139","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2025:23437","name":"RHSA-2025:23437","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2025-12105","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2405992","name":"RHBZ#2405992","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/481"}],"datePublic":"2025-10-23T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-416","description":"Use After Free","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-416: Use After Free","workarounds":[{"lang":"en","value":"Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to a widespread installation base, or stability."}],"timeline":[{"lang":"en","time":"2025-10-23T08:20:47.896Z","value":"Reported to Red Hat."},{"lang":"en","time":"2025-10-23T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Eugene Mutavchi for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-03-19T14:05:42.387Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-10-23T14:54:27.920648Z","id":"CVE-2025-12105","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-23T14:54:44.777Z"}}]}}
