Echo: linux: security update to 6.1.137-1

medium Tenable Self-Hosted Container Security Plugin ID 465723

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: xen-netfront: handle NULL returned by
 xdp_convert_buff_to_frame() The function xdp_convert_buff_to_frame() may return NULL if it fails to
 correctly convert the XDP buffer into an XDP frame due to memory constraints, internal errors, or invalid
 data. Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in
 processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect failure,
 the associated page must be released explicitly if it was previously retained via get_page(). Failing to
 do so may result in a memory leak, as the pages reference count is not decremented. (CVE-2025-37820)

Solution

Update the linux library and its related packages to version 6.1.137-1 or later.
