Subject: [PATCH 0/4] hw/sd: sdhci: Fixes to CVE-2020-17380, CVE-2020-25085, CVE-2021-3409
Date: Mon, 15 Feb 2021 23:11:07 +0800	[thread overview]
Message-ID: <1613401871-59515-1-git-send-email-bmeng.cn@gmail.com> (raw)

From: Bin Meng <bin.meng@windriver.com>

This series includes several fixes to CVE-2020-17380, CVE-2020-25085
and CVE-2021-3409 that are heap-based buffer overflow issues existing
in the sdhci model.

These CVEs are pretty much similar, and were filed using different
reproducers. With this series, current known reproducers I have
cannot be reproduced any more.

The implementation of this model may still have some issues, i.e.:
some codes do not strictly match the spec, but since this series
only aimes to address CVEs, such issue should be fixed in a separate
series in the future, if I have time :)

  hw/sd: sdhci: Don't transfer any data when command time out
  hw/sd: sdhci: Don't write to SDHC_SYSAD register when transfer is in
    progress
  hw/sd: sdhci: Correctly set the controller status for ADMA
  hw/sd: sdhci: Simplify updating s->prnsts in
    sdhci_sdma_transfer_multi_blocks()
