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.
Severity
No CVSS data available.
