How to fix?

Upgrade SLES:15.7 kernel-livepatch-6_4_0-150700_53_84-default to version 1-150700.15.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_84-default package and not the kernel-livepatch-6_4_0-150700_53_84-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

crypto: virtio - bound the akcipher result length

virtio_crypto_dataq_akcipher_callback() sets the result length from the device-reported response length without bounding it to the destination buffer, which was allocated for the original request length. sg_copy_from_buffer() then reads that many bytes from the destination buffer; a backend reporting a larger length over-reads adjacent kernel heap into the caller's scatterlist (an out-of-bounds read).

Clamp the reported length to the originally requested destination length. A conforming device reports no more than that, so valid results are unaffected.
