Echo: linux: security update to 6.1.147-1

medium Tenable Self-Hosted Container Security Plugin ID 465394

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: Fail COMEDI_INSNLIST ioctl if
 n_insns is too large The handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer to hold the
 array of `struct comedi_insn`, getting the length from the `n_insns` member of the `struct
 comedi_insnlist` supplied by the user. The allocation will fail with a WARNING and a stack dump if it is
 too large. Avoid that by failing with an `-EINVAL` error if the supplied `n_insns` value is unreasonable.
 Define the limit on the `n_insns` value in the `MAX_INSNS` macro. Set this to the same value as
 `MAX_SAMPLES` (65536), which is the maximum allowed sum of the values of the member `n` in the array of
 `struct comedi_insn`, and sensible comedi instructions will have an `n` of at least 1. (CVE-2025-38481)

Solution

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