In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: validate assoc response length before status and IE access

cfg80211 rx assoc resp() initialises the status and response-IE fields of cfg80211 connect resp params from the management frame before proving that the frame is long enough for those offsets. S1G and regular association responses also have different IE offsets, but the S1G path only patched resp ie after the unsafe initialiser had already run.

Defer resp ie, resp ie len, and status to after the link-iteration loop. Use a bool to remember whether the frame is S1G, then validate the appropriate minimum length and set all three fields in a single if/else block. Funnel short-frame and SME-reject cleanup through a shared free bss label for the abandon paths.
