Technical description
In the Linux kernel, the following vulnerability has been resolved:
xfs: fix wild memcpy access when formatting ondisk rtrefcount btree roots
LOLLM noticed that the inode btree root formatting methods copy too many
bytes -- there's only one set of keys in node blocks, not two. This
causes memory corruption of whatever's beyond the buffers.
