{"schema_version":"1.7.2","id":"OESA-2026-2140","modified":"2026-05-03T09:55:53Z","published":"2026-05-03T09:55:53Z","upstream":["CVE-2026-41651"],"summary":"PackageKit security update","details":"PackageKit is a D-Bus abstraction layer that allows the session user to manage packages in a secure way using a cross-distro, cross-architecture API.\r\n\r\nSecurity Fix(es):\n\nPackageKit is a D-Bus abstraction layer that allows the user to manage packages in a secure way using a cross-distro, cross-architecture API. PackageKit between and including versions 1.0.2 and 1.3.4 is vulnerable to a time-of-check time-of-use (TOCTOU) race condition on transaction flags that allows unprivileged users to install packages as root and thus leads to a local privilege escalation. This is patched in version 1.3.5.\n\nA local unprivileged user can install arbitrary RPM packages as root, including executing RPM scriptlets, without authentication. The vulnerability is a TOCTOU race condition on `transaction->cached_transaction_flags` combined with a silent state-machine guard that discards illegal backward transitions while leaving corrupted flags in place. Three bugs exist in `src/pk-transaction.c`:\n1. Unconditional flag overwrite (line 4036): `InstallFiles()` writes caller-supplied flags to `transaction->cached_transaction_flags` without checking whether the transaction has already been authorized/started. A second call blindly overwrites the flags even while the transaction is RUNNING.\n2. Silent state-transition rejection (lines 873–882): `pk_transaction_set_state()` silently discards backward state transitions (e.g. `RUNNING` → `WAITING_FOR_AUTH`) but the flag overwrite at step 1 already happened. The transaction continues running with corrupted flags.\n3. Late flag read at execution time (lines 2273–2277): The scheduler's idle callback reads cached_transaction_flags at dispatch time, not at authorization time. If flags were overwritten between authorization and execution, the backend sees the attacker's flags.(CVE-2026-41651)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"PackageKit","purl":"pkg:rpm/openEuler/PackageKit&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.12-11.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["PackageKit-1.1.12-11.oe2203sp4.aarch64.rpm","PackageKit-command-not-found-1.1.12-11.oe2203sp4.aarch64.rpm","PackageKit-debuginfo-1.1.12-11.oe2203sp4.aarch64.rpm","PackageKit-debugsource-1.1.12-11.oe2203sp4.aarch64.rpm","PackageKit-devel-1.1.12-11.oe2203sp4.aarch64.rpm"],"noarch":["PackageKit-help-1.1.12-11.oe2203sp4.noarch.rpm"],"src":["PackageKit-1.1.12-11.oe2203sp4.src.rpm"],"x86_64":["PackageKit-1.1.12-11.oe2203sp4.x86_64.rpm","PackageKit-command-not-found-1.1.12-11.oe2203sp4.x86_64.rpm","PackageKit-debuginfo-1.1.12-11.oe2203sp4.x86_64.rpm","PackageKit-debugsource-1.1.12-11.oe2203sp4.x86_64.rpm","PackageKit-devel-1.1.12-11.oe2203sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS","name":"PackageKit","purl":"pkg:rpm/openEuler/PackageKit&distro=openEuler-24.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.8-5.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["PackageKit-1.2.8-5.oe2403.aarch64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403.aarch64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403.aarch64.rpm","PackageKit-debugsource-1.2.8-5.oe2403.aarch64.rpm","PackageKit-devel-1.2.8-5.oe2403.aarch64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403.aarch64.rpm","PackageKit-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-devel-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-devel-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp3.aarch64.rpm"],"noarch":["PackageKit-help-1.2.8-5.oe2403.noarch.rpm","PackageKit-help-1.2.8-5.oe2403sp1.noarch.rpm","PackageKit-help-1.2.8-5.oe2403sp3.noarch.rpm"],"src":["PackageKit-1.2.8-5.oe2403.src.rpm","PackageKit-1.2.8-5.oe2403sp1.src.rpm","PackageKit-1.2.8-5.oe2403sp3.src.rpm"],"x86_64":["PackageKit-1.2.8-5.oe2403.x86_64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403.x86_64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403.x86_64.rpm","PackageKit-debugsource-1.2.8-5.oe2403.x86_64.rpm","PackageKit-devel-1.2.8-5.oe2403.x86_64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403.x86_64.rpm","PackageKit-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-devel-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-1.2.8-5.oe2403sp3.x86_64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp3.x86_64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp3.x86_64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp3.x86_64.rpm","PackageKit-devel-1.2.8-5.oe2403sp3.x86_64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp3.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"PackageKit","purl":"pkg:rpm/openEuler/PackageKit&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.8-5.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["PackageKit-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-devel-1.2.8-5.oe2403sp1.aarch64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp1.aarch64.rpm"],"noarch":["PackageKit-help-1.2.8-5.oe2403sp1.noarch.rpm"],"src":["PackageKit-1.2.8-5.oe2403sp1.src.rpm"],"x86_64":["PackageKit-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-devel-1.2.8-5.oe2403sp1.x86_64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"PackageKit","purl":"pkg:rpm/openEuler/PackageKit&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.8-5.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["PackageKit-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-command-not-found-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-debuginfo-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-debugsource-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-devel-1.2.8-5.oe2403sp3.aarch64.rpm","PackageKit-gtk3-module-1.2.8-5.oe2403sp3.aarch64.rpm"],"noarch":["PackageKit-help-1.2.8-5.oe2403sp3.noarch.rpm"],"sr
