CVE-2024-0217: Packagekitd: use-after-free in idle function callback
First published: Wed Jan 03 2024(Updated: )
A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost.
