commit 6dbef74a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I7T4O5
CVE: CVE-2023-20593

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=i6dbef74aeb090d6bee7d64ef3fa82ae6fa53f271



--------------------------------

Commit 522b1d69 ("x86/cpu/amd: Add a Zenbleed fix") provided a fix
for the Zen2 VZEROUPPER data corruption bug affecting a range of CPU
models, but the AMD Custom APU 0405 found on SteamDeck was not listed,
although it is clearly affected by the vulnerability.

Add this CPU variant to the Zenbleed erratum list, in order to
unconditionally enable the fallback fix until a proper microcode update
is available.
