Alpine: multiple haveged packages: security update to 1.9.21-r0

high Tenable Cloud Security Plugin ID 442234

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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`. (CVE-2026-41054)

Solution

Update the haveged library and its related packages to version 1.9.21-r0 or later.
