NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150400_24_116-default package and not the kernel-livepatch-5_14_21-150400_24_116-default package as distributed by SLES. See How to fix? for SLES:15.4 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.
