CVE-2026-29111 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:7.
NVD Description
Note: Versions mentioned in the description apply only to the upstream systemd-python package and not the systemd-python package as distributed by RHEL.
systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.
