Description (CNA)
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.
