Technical description

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

ASoC: amd: acp-sdw-legacy: Bound DAI link iteration

create_sdw_dailinks() walks soc_dais until it finds an entry with

initialised cleared, but soc_dais is allocated with exactly num_ends

entries. If all entries are initialised, the loop reads past the end of

the array.

This was reported by KASAN:

BUG: KASAN: slab-out-of-bounds in mc_probe+0x26b3/0x2774 [snd_acp_sdw_legacy_mach]

Read of size 1

Pass the allocated entry count to create_sdw_dailinks() and stop before

reading past the array.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
