CVE-2022-49893: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix cxl_region leak, cleanup targets at region delete When a region is deleted any targets that have been previously assigned to that region hold references to it. Trigger those references to drop by detaching all targets at unregister_region() time. Otherwise that region object will leak as userspace has lost the ability to detach targets once region sysfs is torn down.

Affected products

• Linux Linux Kernel: from 6.0, before 6.0.8 (fixed in 6.0.8); version 6.1 only
