This link is maintained to preserve external references.\n\n## Original Description\nThe MongoDB Python Driver's binary accelerator can read outside a buffer when an application decodes malformed BSON containing a truncated regular-expression element without a trailing NUL byte. An actor who can supply BSON to the documented decode or decode_all API can cause the application process to terminate when the C extension is loaded. The driver's normal database wire-protocol path does not reach this code.","public_affected_ranges":[">= 3.9.0, <= 4.18.2"]}],"null_published_at":"2026-10-31T22:13:27.124Z","source_updated_at":"2026-10-27T15:36:26.000Z","source_disclosed_at":"2026-10-08T21:33:28.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:56:51.534Z"}],"next_cursor":null,"snapshot_revision":"42594"}
