Echo: linux: security update to 6.1.147-1

medium Tenable Self-Hosted Container Security Plugin ID 460622

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: comedi: Fix initialization of data for
instructions that write to subdevice Some Comedi subdevice instruction handlers are known to access
instruction data elements beyond the first `insn->n` elements in some cases. The `do_insn_ioctl()` and
`do_insnlist_ioctl()` functions allocate at least `MIN_SAMPLES` (16) data elements to deal with this, but
they do not initialize all of that. For Comedi instruction codes that write to the subdevice, the first
`insn->n` data elements are copied from user-space, but the remaining elements are left uninitialized.
That could be a problem if the subdevice instruction handler reads the uninitialized data. Ensure that the
first `MIN_SAMPLES` elements are initialized before calling these instruction handlers, filling the
uncopied elements with 0. For `do_insnlist_ioctl()`, the same data buffer elements are used for handling a
list of instructions, so ensure the first `MIN_SAMPLES` elements are initialized for each instruction that
writes to the subdevice. (CVE-2025-38478)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
