      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: fix interlaced plain identification for encoded extents\n\nOnly plain data whose start position and on-disk physical length are\nboth aligned to the block size should be classified as interlaced\nplain extents. Otherwise, it must be treated as shifted plain extents.\n\nThis issue was found by syzbot using a crafted compressed image\ncontaining plain extents with unaligned physical lengths, which can\ncause OOB read in z_erofs_transform_plain().",
