Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 460603

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: dmaengine: qcom: bam_dma: Fix DT error
handling for num-channels/ees When we don't have a clock specified in the device tree, we have no way to
ensure the BAM is on. This is often the case for remotely-controlled or remotely-powered BAM instances. In
this case, we need to read num-channels from the DT to have all the necessary information to complete
probing. However, at the moment invalid device trees without clock and without num-channels still continue
probing, because the error handling is missing return statements. The driver will then later try to read
the number of channels from the registers. This is unsafe, because it relies on boot firmware and lucky
timing to succeed. Unfortunately, the lack of proper error handling here has been abused for several
Qualcomm SoCs upstream, causing early boot crashes in several situations [1, 2]. Avoid these early crashes
by erroring out when any of the required DT properties are missing. Note that this will break some of the
existing DTs upstream (mainly BAM instances related to the crypto engine). However, clearly these DTs have
never been tested properly, since the error in the kernel log was just ignored. It's safer to disable the
crypto engine for these broken DTBs. [1]:
