Container suse/sle-micro-rancher/5.3:latest: Authentication Bypass by Primary Weakness
CVE-2026-41054 is a high-severity authentication bypass by primary weakness vulnerability in Container suse/sle-micro-rancher/5.3:latest from SUSE, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 1.9.14-150400.3.11.1 as the first without the flaw, so updating Container suse/sle-micro-rancher/5.3:latest to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.18% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Container suse/sle-micro-rancher/5.3:latest to 1.9.14-150400.3.11.1 or a later version.
- Update Container suse/sle-micro-rancher/5.4:latest to 1.9.14-150400.3.11.1 or a later version.
- Update Container suse/sle-micro/5.5:latest to 1.9.14-150400.3.11.1 or a later version.

Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. Scored by CNA (suse.de).
Official description
In `src/havegecmd.c`, the `socket_handler` function performs a credential check on the abstract UNIX socket (`\0/sys/entropy/haveged`). However, while it detects if the connecting user is not root (`cred.uid != 0`) and prepares a negative acknowledgement (`ASCII_NAK`), it **fails to stop execution**. The code proceeds to the `switch` statement, allowing any local unprivileged user to execute privileged commands such as `MAGIC_CHROOT`.

The underlying weakness: Authentication Bypass by Primary Weakness
The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
