CVE-2026-23160

Medium

In the Linux kernel, the following vulnerability has been resolved: octeon_ep: Fix memory leak in octep_device_setup() In octep_device_setup(), if octep_ctrl_net_init() fails, the function returns directly without unmapping the mapped resources and freeing the allocated configuration memory. Fix this by jumping to the unsupported_dev label, which performs the necessary cleanup. This aligns with the error handling logic of other paths in this function. Compile tested only. Issue found using a prototype static analysis tool and code review.
