| Subject: CVE-2022-49673: dm raid: fix KASAN warning in raid5_add_disks |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| dm raid: fix KASAN warning in raid5_add_disks |
| |
| There's a KASAN warning in raid5_add_disk when running the LVM testsuite. |
| The warning happens in the test |
| lvconvert-raid-reshape-linear_to_raid6-single-type.sh. We fix the warning |
| by verifying that rdev->saved_raid_disk is within limits. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49673 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
