CVE-2026-74333

EUVD-2026-59480
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.
