Description

In the Linux kernel, the following vulnerability has been resolved: f2fs: assign CURSEG_ALL_DATA_ATGC if blkaddr is valid mkdir /mnt/test/comp f2fs_io setflags compression /mnt/test/comp dd if=/dev/zero of=/mnt/test/comp/testfile bs=16k count=1 truncate --size 13 /mnt/test/comp/testfile In the above scenario, we can get a BUG_ON. kernel BUG at fs/f2fs/segment.c:3589!
