CVE-2026-34772

CVSS v3.1

5.8

Medium

AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:L

Impact

Apps that allow downloads and programmatically destroy sessions may be vulnerable to a use-after-free. If a session is torn down while a native save-file dialog is open for a download, dismissing the dialog dereferences freed memory, which may lead to a crash or memory corruption.
Apps that do not destroy sessions at runtime, or that do not permit downloads, are not affected.

Workarounds

Avoid destroying sessions while a download save dialog may be open. Cancel pending downloads before session teardown.

Fixed Versions

  • 41.0.0-beta.7
  • 40.7.0
  • 39.8.0
  • 38.8.6
