Title
rtw88: fix memory overrun and memory leak during hw_scan
Summary
In the Linux kernel, the following vulnerability has been resolved: rtw88: fix memory overrun and memory leak during hw_scan Previously we allocated less memory than actual required, overwrite to the buffer causes the mm module to complaint and raise access violation faults. Along with potential memory leaks when returned early. Fix these by passing the correct size and proper deinit flow.
Severity ?
5.5 (Medium)
