Overview\n\nA flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.\n\n## Affected\n\n- `glib < 2.88.1`\n- `enterprise_linux = 6.0`\n- `enterprise_linux = 7.0`\n- `enterprise_linux = 8.0`\n- `enterprise_linux = 9.0`\n- `enterprise_linux = 10.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `glib 2.88.1`\n\n## Vendor advisories\n\n- **RHSA-2026:51183** · Red Hat · fixed in: Red Hat Enterprise Linux Server (v. 7 ELS), Red Hat Enterprise Linux Server Optional (v. 7 ELS) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51183)\n- **RHSA-2026:51185** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0), Red Hat Enterprise Linux BaseOS EUS (v. 10.0), Red Hat Enterprise Linux CodeReady Linux Builder EUS (v. 10.0) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51185)\n- **RHSA-2026:42063** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10), Red Hat Enterprise Linux BaseOS (v. 10), Red Hat Enterprise Linux CodeReady Linux Builder (v. 10) · released 2026-07-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:42063)\n- **RHSA-2026:51176** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.2), Red Hat Enterprise Linux BaseOS E4S (v.9.2) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51176)\n- **RHSA-2026:51177** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.4), Red Hat Enterprise Linux BaseOS E4S (v.9.4) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51177)\n- **RHSA-2026:51175** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6), Red Hat Enterprise Linux BaseOS EUS (v.9.6), Red Hat CodeReady Linux Builder EUS (v.9.6) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51175)\n- **RHSA-2026:42089** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9), Red Hat Enterprise Linux BaseOS (v. 9), Red Hat Enterprise Linux CodeReady Linux Builder (v. 9) · released 2026-07-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:42089)\n- **RHSA-2026:42090** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS (v. 8), Red Hat Enterprise Linux CRB (v. 8) · released 2026-07-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:42090)\n- **RHSA-2026:51184** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS AUS (v.8.4), Red Hat Enterprise Linux BaseOS EUS EXTENSION (v.8.4) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51184)\n- **RHSA-2026:51181** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS AUS (v.8.6), Red Hat Enterprise Linux BaseOS EUS EXTENSION (v.8.6) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51181)\n- **RHSA-2026:51182** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS E4S (v.8.8), Red Hat Enterprise Linux BaseOS TUS (v.8.8) · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51182)\n- **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 10 · updated 2026-10-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-58016.json)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
