Vulnerability Title
dm: fix dm_blk_report_zones
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
dm: fix dm_blk_report_zones
If dm_get_live_table() returned NULL, dm_put_live_table() was never
called. Also, it is possible that md->zone_revalidate_map will change
while calling this function. Only read it once, so that we are always
using the same value. Otherwise we might miss a call to
dm_put_live_table().
Finally, while md->zone_revalidate_map is set and a process is calling
blk_revalidate_disk_zones() to set up the zone append emulation
resources, it is possible that another process, perhaps triggered by
blkdev_report_zones_ioctl(), will call dm_blk_report_zones(). If
blk_revalidate_disk_zones() fails, these resources can be freed while
the other process is still using them, causing a use-after-free error.
blk_revalidate_disk_zones() will only ever be called when initially
setting up the zone append emulation resources, such as when setting up
a zoned dm-crypt table for the first time. Further table swaps will not
set md->zone_revalidate_map or call blk_revalidate_disk_zones().
However it must be called using the new table (referenced by
md->zone_revalidate_map) and the new queue limits while the DM device is
suspended. dm_blk_report_zones() needs some way to distinguish between a
call from blk_revalidate_disk_zones(), which must be allowed to use
md->zone_revalidate_map to access this not yet activated table, and all
other calls to dm_blk_report_zones(), which should not be allowed while
the device is suspended and cannot use md->zone_revalidate_map, since
the zone resources might be freed by the process currently calling
blk_revalidate_disk_zones().
Solve this by tracking the process that sets md->zone_revalidate_map in
dm_revalidate_zones() and only allowing that process to make use of it
in dm_blk_report_zones().
