Echo: linux: security update to 6.1.153-1

high Tenable Cloud Security Plugin ID 461836

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: pcl726: Prevent invalid irq
number The reproducer passed in an irq number(0x80008000) that was too large, which triggered the oob.
Added an interrupt number check to prevent users from passing in an irq number that was too large. If
`it->options[1]` is 31, then `1 << it->options[1]` is still invalid because it shifts a 1-bit into the
sign bit (which is UB in C). Possible solutions include reducing the upper bound on the `it->options[1]`
value to 30 or lower, or using `1U << it->options[1]`. The old code would just not attempt to request the
IRQ if the `options[1]` value were invalid. And it would still configure the device without interrupts
even if the call to `request_irq` returned an error. So it would be better to combine this test with the
test below. (CVE-2025-39685)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
