**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the bpf arena logic in the Linux kernel, which did not account for the mremap operation. This led to a potential use-after-free scenario in the arena vm close function. To prevent this, a reference count was added for multiple mmap events. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
