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/raid10: prevent soft lockup while
flush writes Currently, there is no limit for raid1/raid10 plugged bio. While flushing writes, raid1 has
cond_resched() while raid10 doesn't, and too many writes can cause soft lockup. Follow up soft lockup can
be triggered easily with writeback test for raid10 with ramdisks: watchdog: BUG: soft lockup - CPU#10
stuck for 27s! [md0_raid10:1293] Call Trace: <TASK> call_rcu+0x16/0x20 put_object+0x41/0x80

raid10d+0xac/0x1ed0 Fix the problem by adding cond_resched() to raid10 like what raid1 did. Note that
unlimited plugged bio still need to be optimized, for example, in the case of lots of dirty pages
writeback, this will take lots of memory and io will spend a long time in plug, hence io latency is bad.
(CVE-2023-53151)
