3Description
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.
Analysis
The Linux kernel's octeon_ep driver fails to properly clean up allocated memory and mapped resources when the octep_ctrl_net_init() function fails during device setup, resulting in a local denial of service condition. An authenticated local attacker could trigger this memory leak by causing the initialization to fail, exhausting system memory over time. …
