Golang: stdlib: security update to 1.25.9stdlib: security update to 1.26.2

medium Tenable Self-Hosted Container Security Plugin ID 439983

Description

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

 - On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress,
 Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux
 fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink
 traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink
 lying outside the root, so the impact is limited to cases where the target is replaced with a symlink
 between the check and operation. (CVE-2026-32282)

Solution

Update the stdlib library and its related packages to version 1.25.9 or later.
