The record is created +by a G_PRIORITY_HIGH idle queued from a GDBus message filter on the worker +thread; that idle is not reliably ordered against the method dispatch, so +under concurrent bursts a call occasionally arrives first, get_pkcs11_session +asserts, the negotiate helper returns FALSE without a GError, OpenSession +completes with a NULL body, and g_variant_new aborts the daemon. systemd +restarts it, the unlocked state is gone, and the next request shows the +keyring password dialog. + +This is upstream bug 190 (also 194, 195, 196, 199), present in 48 through +51.1, unmerged fix in merge request !112 since 2026-08-25. On ratio the first +abort was 2026-10-11 19:03:59, the evening the ChatGPT desktop app was +installed; openai/codex issue 51694 documents its bundled app-server opening +a fresh Secret Service connection per keyring read in bursts and crashing +gnome-keyring with exactly this signature. The same-day glib and keyring +upgrades were a coincidence: the VM reproduced the crash on 50.0 as well. + +A second, pre-existing defect surfaced while testing the fix: the filter's +alias rewrite reads the alias table on the worker thread while the main +thread replaces and frees its entries on every client registration. +AddressSanitizer confirmed it as a heap-use-after-free read in +gkd_secret_util_build_path from rewrite_default_alias, freed by +g_hash_table_replace in update_default. Stock and !112 both carry it. + +* Fix (packages/gnome-keyring, patch 0002) + +- Register the client at the point of use in get_pkcs11_session and + publish_dispatch (as !112). +- aes_negotiate and plain_negotiate return G_DBUS_ERROR_FAILED instead of + asserting; OpenSession branches on the return value and never completes + with a NULL body (as !112). +- lookup_collection takes the caller's PKCS#11 session before resolving an + alias, so the lazy registration cannot free a borrowed alias string (the + earlier reviewer's use-after-free finding). +- The property-path lookup returns NO_SUCH_OBJECT instead of asserting when + there is no session (upstream 195). +- A mutex guards the alias table; the worker-thread filter and store_default + take owned copies under it; the default alias is replaced only when its + value changes so main-thread borrowers stay valid. + +Packaged as Arch's own recipe for 1:51.1-1 (Cinnamon patch kept, arch-meson, +selinux disabled) built from GNOME's release tarball (published sha256 +dfe7adc5876ef0670e7eba2907799bdbb8875ce58bb4208e1a52169bd16a47ca) plus the +patch, at pkgrel 1.1: above stock, below any future 1:51.1-2 or 51.2, so a +normal upgrade replaces it when a real fix lands.
