CVE-2022-49673 Details
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.
A vulnerability has been identified in the Linux kernel's dm raid component, specifically within the raid5_add_disks function. This issue triggers a KASAN (Kernel Address Sanitizer) warning during the LVM testsuite, particularly in the testlvconvert-raid-reshape-linear_to_raid6-single-type.sh script. The warning arises because the 'saved_raid_disk' value of a certain 'rdev' (raid device) is out of acceptable bounds. The vulnerability has been addressed by adding a verification step to ensure that this value remains within the proper limits.
