Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 458381

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: thunderbolt: Validate XDomain request
 packet size before type cast tb_xdp_handle_request() casts the received packet buffer to protocol-specific
 structs without verifying that the allocation is large enough for the target type. A peer can send a
 minimal XDomain packet that passes the generic header length check but is shorter than the struct accessed
 after the cast, causing out-of- bounds reads from the kmemdup allocation. Plumb the packet length through
 xdomain_request_work and validate it against the expected struct size before each cast. (CVE-2026-53147)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
