Echo: linux: security update to 6.1.148-1

high Tenable Self-Hosted Container Security Plugin ID 465225

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: f2fs: fix KMSAN uninit-value in
 extent_info usage KMSAN reported a use of uninitialized value in `__is_extent_mergeable()` and
 `__is_back_mergeable()` via the read extent tree path. The root cause is that `get_read_extent_info()`
 only initializes three fields (`fofs`, `blk`, `len`) of `struct extent_info`, leaving the remaining fields
 uninitialized. This leads to undefined behavior when those fields are accessed later, especially during
 extent merging. Fix it by zero-initializing the `extent_info` struct before population. (CVE-2025-38579)

Solution

Update the linux library and its related packages to version 6.1.148-1 or later.
