Echo: linux: security update to 6.12.25-1

high Tenable Cloud Security Plugin ID 458804

Description

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

 - In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix overflow in dacloffset
 bounds check The dacloffset field was originally typed as int and used in an unchecked addition, which
 could overflow and bypass the existing bounds check in both smb_check_perm_dacl() and smb_inherit_dacl().
 This could result in out-of-bounds memory access and a kernel crash when dereferencing the DACL pointer.
 This patch converts dacloffset to unsigned int and uses check_add_overflow() to validate access to the
 DACL. (CVE-2025-22039)

Solution

Update the linux library and its related packages to version 6.12.25-1 or later.
