CVE-2024-26763 – dm-crypt: don't modify the data when using authenticated encryption
https://notcve.org/view.php?id=CVE-2024-26763
03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: dm-crypt: don't modify the data when using authenticated encryption It was said that authenticated encryption could produce invalid tag when the data that is being encrypted is modified [1]. So, fix this problem by copying the data into the clone bio first and then encrypt them inside the clone bio. This may reduce performance, but it is needed to prevent the user from corrupting the device by writing data with O_DIRECT and modifying them a... • https://git.kernel.org/stable/c/43a202bd552976497474ae144942e32cc5f34d7e •
CVE-2024-26758 – md: Don't ignore suspended array in md_check_recovery()

03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: md: Don't ignore suspended array in md_check_recovery() mddev_suspend() never stop sync_thread, hence it doesn't make sense to ignore suspended array in md_check_recovery(), which might cause sync_thread can't be unregistered. After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following hang can be triggered by test shell/integrity-caching.sh: 1) suspend the array: raid_postsuspend mddev_suspend 2) stop the array: raid_dtr md_stop ... • https://git.kernel.org/stable/c/68866e425be2ef2664aa5c691bb3ab789736acf5 • CWE-20: Improper Input Validation CWE-129: Improper Validation of Array Index •
CVE-2024-26757 – md: Don't ignore read-only array in md_check_recovery()
https://notcve.org/view.php?id=CVE-2024-26757
03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: md: Don't ignore read-only array in md_check_recovery() Usually if the array is not read-write, md_check_recovery() won't register new sync_thread in the first place. And if the array is read-write and sync_thread is registered, md_set_readonly() will unregister sync_thread before setting the array read-only. md/raid follow this behavior hence there is no problem.

CVE-2024-26756 – md: Don't register sync_thread for reshape directly

03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: md: Don't register sync_thread for reshape directly Currently, if reshape is interrupted, then reassemble the array will register sync_thread directly from pers->run(), in this case 'MD_RECOVERY_RUNNING' is set directly, however, there is no guarantee that md_do_sync() will be executed, hence stop_sync_thread() will hang because 'MD_RECOVERY_RUNNING' can't be cleared. Last patch make sure that md_do_sync() will set MD_RECOVERY_DONE, however... • https://git.kernel.org/stable/c/f67055780caac6a99f43834795c43acf99eba6a6 •
