+Subject: [PATCH 3/8] ext4: Fix integer overflow in ext4fs_read_symlink()
+
+While zalloc() takes a size_t type, adding 1 to the le32 variable
+will overflow.
+A carefully crafted ext4 filesystem can exhibit an inode size of 0xffffffff
+and as consequence zalloc() will do a zero allocation.
+
+Later in the function the inode size is again used for copying data.
+So an attacker can overwrite memory.
+
+Avoid the overflow by using the __builtin_add_overflow() helper.
