CVE-2026-97600

A flaw was found in the Linux kernel's CC2520 radio driver. During device removal, an interrupt handler can queue background work after the driver's private data has been released, resulting in a use-after-free condition. A local user with privileges to disconnect or unbind the device could explo...
