CVE-2024-43820

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dm-raid: Fix WARN_ON_ONCE check for sync_thread in raid_resume<br /> <br /> rm-raid devices will occasionally trigger the following warning when<br /> being resumed after a table load because DM_RECOVERY_RUNNING is set:<br /> <br /> WARNING: CPU: 7 PID: 5660 at drivers/md/dm-raid.c:4105 raid_resume+0xee/0x100 [dm_raid]<br /> <br /> The failing check is:<br /> WARN_ON_ONCE(test_bit(MD_RECOVERY_RUNNING, &amp;mddev-&gt;recovery));<br /> <br /> This check is designed to make sure that the sync thread isn&amp;#39;t<br /> registered, but md_check_recovery can set MD_RECOVERY_RUNNING without<br /> the sync_thread ever getting registered. Instead of checking if<br /> MD_RECOVERY_RUNNING is set, check if sync_thread is non-NULL.
