How to fix?

Upgrade SLES:15.5 kernel-64kb-devel to version 5.14.21-150500.55.59.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64kb-devel package and not the kernel-64kb-devel package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

crypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ

The commit referenced in the Fixes tag removed the 'break' from the else branch in qcom_rng_read(), causing an infinite loop whenever 'max' is not a multiple of WORD_SZ. This can be reproduced e.g. by running:

kcapi-rng -b 67 &gt;/dev/null

There are many ways to fix this without adding back the 'break', but they all seem more awkward than simply adding it back, so do just that.

Tested on a machine with Qualcomm Amberwing processor.
