- Summary
- ext4: fix another off-by-one fsmap error on 1k block filesystems
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix another off-by-one fsmap error on 1k block filesystems
Apparently syzbot figured out that issuing this FSMAP call:
struct fsmaphead cmd = { .fmhcount = ...; .fmhkeys = { { .fmrdevice = /* ext4 dev /, .fmr_physical = 0, }, { .fmr_device = / ext4 dev */, .fmrphysical = 0, }, }, ... }; ret = ioctl(fd, FSIOC_GETFSMAP, &cmd);
Produces this crash if the underlying filesystem is a 1k-block ext4 filesystem:

For GETFSMAP calls, the caller selects a physical block device by writing its block number into fsmaphead.fmhkeys[01].fmrdevice. To query mappings for a subrange of the device, the starting byte of the range is written to fsmaphead.fmhkeys[0].fmrphysical and the last byte of the range goes in fsmaphead.fmhkeys[1].fmr_physical.
IOWs, to query what mappings overlap with bytes 3-14 of /dev/sda, you'd set the inputs as follows:
fmh_keys[0] = { .fmr_device = major(8, 0), .fmr_physical = 3}, fmh_keys[1] = { .fmr_device = major(8, 0), .fmr_physical = 14},Which would return you whatever is mapped in the 12 bytes starting at physical offset 3.
The crash is due to insufficient range validation of keys[1] in ext4getfsmapdatadev. On 1k-block filesystems, block 0 is not part of the filesystem, which means that sfirstdatablock is nonzero. ext4getgroupnoandoffset subtracts this quantity from the blocknr argument before cracking it into a group number and a block number within a group. IOWs, block group 0 spans blocks 1-8192 (1-based) instead of 0-8191 (0-based) like what happens with larger blocksizes.
The net result of this encoding is that blocknr < sfirstdatablock is not a valid input to this function. The endfsb variable is set from the keys that are copied from userspace, which means that in the above example, its value is zero. That leads to an underflow here:
blocknr = blocknr - le32_to_cpu(es->s_first_data_block);The division then operates on -1:
offset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) >> EXT4_SB(sb)->s_cluster_bits;Leaving an impossibly large group number (2^32-1) in blocknr. ext4getfsmapcheck_keys checked that keys[0 ---truncated---
