Also, it is possible that md->zone_revalidate_map will change\nwhile calling this function. Only read it once, so that we are always\nusing the same value. Otherwise we might miss a call to\ndm_put_live_table().\n\nFinally, while md->zone_revalidate_map is set and a process is calling\nblk_revalidate_disk_zones() to set up the zone append emulation\nresources, it is possible that another process, perhaps triggered by\nblkdev_report_zones_ioctl(), will call dm_blk_report_zones(). If\nblk_revalidate_disk_zones() fails, these resources can be freed while\nthe other process is still using them, causing a use-after-free error.\n\nblk_revalidate_disk_zones() will only ever be called when initially\nsetting up the zone append emulation resources, such as when setting up\na zoned dm-crypt table for the first time. Further table swaps will not\nset md->zone_revalidate_map or call blk_revalidate_disk_zones().\nHowever it must be called using the new table (referenced by\nmd->zone_revalidate_map) and the new queue limits while the DM device is\nsuspended. dm_blk_report_zones() needs some way to distinguish between a\ncall from blk_revalidate_disk_zones(), which must be allowed to use\nmd->zone_revalidate_map to access this not yet activated table, and all\nother calls to dm_blk_report_zones(), which should not be allowed while\nthe device is suspended and cannot use md->zone_revalidate_map, since\nthe zone resources might be freed by the process currently calling\nblk_revalidate_disk_zones().\n\nSolve this by tracking the process that sets md->zone_revalidate_map in\ndm_revalidate_zones() and only allowing that process to make use of it\nin dm_blk_report_zones()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/md/dm-core.h","drivers/md/dm-zone.c"],"versions":[{"version":"f211268ed1f9bdf48f06a3ead5f5d88437450579","lessThan":"f9c1bdf24615303d48a2d0fd629c88f3189563aa","status":"affected","versionType":"git"},{"version":"f211268ed1f9bdf48f06a3ead5f5d88437450579","lessThan":"d19bc1b4dd5f322980b1f05f79b2ea4f0db10920","status":"affected","versionType":"git"},{"version":"f211268ed1f9bdf48f06a3ead5f5d88437450579","lessThan":"37f53a2c60d03743e0eacf7a0c01c279776fef4e","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/md/dm-core.h","drivers/md/dm-zone.c"],"versions":[{"version":"6.10","status":"affected"},{"version":"0","lessThan":"6.10","status":"unaffected","versionType":"semver"},{"version":"6.12.34","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.3","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.12.34"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.15.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f9c1bdf24615303d48a2d0fd629c88f3189563aa"},{"url":"https://git.kernel.org/stable/c/d19bc1b4dd5f322980b1f05f79b2ea4f0db10920"},{"url":"https://git.kernel.org/stable/c/37f53a2c60d03743e0eacf7a0c01c279776fef4e"}],"title":"dm: fix dm_blk_report_zones","x_generator":{"engine":"bippy-1.2.0"}}}}
