CVE-2024-39495 is a high-severity use-after-free vulnerability in the Linux kernel's Greybus subsystem. It arises from a race condition where the gb_interface_release function can free an 'intf' object before a scheduled gb_interface_mode_switch_work can execute, leading to an attempt to access freed memory. This local vulnerability (CVSS 7.8) could allow an attacker to achieve high confidentiality, integrity, and availability impacts. There is currently no public exploit code available, nor is there any indication of active exploitation or significant community discussion.
