CVE-2024-26962 dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape

In the Linux kernel, the following vulnerability has been resolved: dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape For raid456, if reshape is still in progress, then IO across reshape position will wait for reshape to make progress. However, for dm-raid, in...

CVE-2024-26757

In the Linux kernel, the following vulnerability has been resolved: md: Don't ignore read-only array in mdcheckrecovery Usually if the array is not read-write, mdcheckrecovery won't register new syncthread in the first place. And if the array is read-write and syncthread is registered,...

CVE-2024-26756

In the Linux kernel, the following vulnerability has been resolved: md: Don't register syncthread for reshape directly Currently, if reshape is interrupted, then reassemble the array will register syncthread directly from pers-run, in this case 'MDRECOVERYRUNNING' is set directly, however, there ...

CVE-2024-26758

CVE-2024-26758 relates to the Linux kernel’s md subsystem: md_check_recovery() previously could fail to clear MD_RECOVERY_RUNNING when suspended, allowing a hanging sync_thread during suspend/resume of md devices. The fix ignores the suspended array in md_check_recovery(), addressing a hang where...

CVE-2024-26756

The CVE-2024-26756 issue affects the Linux kernel’s md (multidisk) subsystem, specifically the raid reshape path. The root cause was registering the sync_thread directly from pers->run() during an interrupted reshape, which could set MD_RECOVERY_RUNNING without guaranteeing that md_do_sync() w...
