Title
md: raid1: fix potential OOB in raid1_remove_disk()
Summary
In the Linux kernel, the following vulnerability has been resolved: md: raid1: fix potential OOB in raid1_remove_disk() If rddev->raid_disk is greater than mddev->raid_disks, there will be an out-of-bounds in raid1_remove_disk(). We have already found similar reports as follows: 1) commit d17f744e883b ("md-raid10: fix KASAN warning") 2) commit 1ebc2cec0b7d ("dm raid: fix KASAN warning in raid5_remove_disk") Fix this bug by checking whether the "number" variable is valid.
