Description
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: remove station if connection prep fails
If connection preparation fails for MLO connections, then the
interface is completely reset to non-MLD. In this case, we must
not keep the station since it's related to the link of the vif
being removed. Delete an existing station. Any "new_sta" is
already being removed, so that doesn't need changes.
This fixes a use-after-free/double-free in debugfs if that's
enabled, because a vif going from MLD (and to MLD, but that's
not relevant here) recreates its entire debugfs.

Exploitability
CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-825 | The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid. |
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |
