In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci: Fix max_seg_size for 64KiB PAGE_SIZE
blk_queue_max_segment_size() ensured:
if (max_size < PAGE_SIZE)
max_size = PAGE_SIZE;
whereas:
blk_validate_limits() makes it an error:
if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE))
return -EINVAL;
The change from one to the other, exposed sdhci which was setting maximum
segment size too low in some circumstances.
Fix the maximum segment size when it is too low.
