AI-suggested
A patch is available and should be applied to affected linux-hwe-edge kernel versions. The vendor advisory (Ubuntu USN-8876-1) confirms that this and other Linux kernel vulnerabilities have been fixed. Users should update to the fixed kernel versions to remediate this issue.
Description
A vulnerability in the Linux kernel's device mapper (dm_early_create) was fixed to address improper freeing of a used table on dm_resume failure. If dm_resume fails, the kernel previously attempted to free a table that was already instantiated differently, potentially causing system instability. This issue affects specific versions of the linux-hwe-edge kernel and has been resolved with a patch.
