Echo: linux: security update to 6.7.7-1

medium Tenable Cloud Security Plugin ID 460338

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following
hang can be triggered by test shell/integrity-caching.sh: 1) array is read-only. dm-raid update super
block: rs_update_sbs ro = mddev->ro mddev->ro = 0 -> set array read-write md_update_sb 2) register new
sync thread concurrently. 3) dm-raid set array back to read-only: rs_update_sbs mddev->ro = ro 4) stop the
array: raid_dtr md_stop stop_sync_thread set_bit(MD_RECOVERY_INTR, &mddev->recovery);
md_wakeup_thread_directly(mddev->sync_thread); wait_event(..., !test_bit(MD_RECOVERY_RUNNING,
&mddev->recovery)) 5) sync thread done: md_do_sync set_bit(MD_RECOVERY_DONE, &mddev->recovery);
md_wakeup_thread(mddev->thread); 6) daemon thread can't unregister sync thread: md_check_recovery if
(!md_is_rdwr(mddev) && !test_bit(MD_RECOVERY_NEEDED, &mddev->recovery)) return; -> -> MD_RECOVERY_RUNNING
can't be cleared, hence step 4 hang; The root cause is that dm-raid manipulate 'mddev->ro' by itself,
however, dm-raid really should stop sync thread before setting the array read-only. Unfortunately, I need
to read more code before I can refacter the handler of 'mddev->ro' in dm-raid, hence let's fix the problem
the easy way for now to prevent dm-raid regression. (CVE-2024-26757)
