Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 458128

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: usb: gadget: f_uac1_legacy: validate
control request size f_audio_complete() copies req->length bytes into a 4-byte stack variable: u32 data =
0; memcpy(&data, req->buf, req->length); req->length is derived from the host-controlled USB request path,
which can lead to a stack out-of-bounds write. Validate req->actual against the expected payload size for
the supported control selectors and decode only the expected amount of data. This avoids copying a host-
influenced length into a fixed-size stack object. (CVE-2026-31720)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
