- Summary
- mmc: sdhci: Fix max_seg_size for 64KiB PAGE_SIZE
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci: Fix maxsegsize for 64KiB PAGE_SIZE
blkqueuemaxsegmentsize() ensured:
if (max_size < PAGE_SIZE) max_size = PAGE_SIZE;whereas:
blkvalidatelimits() 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.
