In the Linux kernel, the following vulnerability has been resolved: ext4: inline: fix len overflow in ext4_prepare_inline_data When running the following code on an ext4 filesystem with inline_data feature enabled, it will lead to the bug below. fd = open("file1", O_RDWR | O_CREAT | O_TRUNC, 0666); ftruncate(fd, 30); pwrite(fd, "a", 1, (1UL EXT4_I(inode)->i_inline_size); at ext4_write_inline_data. Fix it by using a loff_t type for the len parameter in ext4_prepare_inline_data instead of an unsigned int.
