[SRU][J][PATCH 0/1] CVE-2023-52593

[alice.munduruca at canonical.com]

From: "Alice C. Munduruca" <alice.munduruca at canonical.com>

[ Impact ]

No check is made in `wfx_set_mfp_ap` in case the function
`ieee80211_beacon_get` returns a null pointer in case of error.
As a result, we add a check to ensure a null pointer dereference
does not occur.

[ Fix ]

Jammy: Cherry-Picked and merged from torvalds/linux --
       `wfx_hif_set_mfp` was changed to the applicable
       `hif_set_mfp`.

[ Test Plan ]

Compile and boot tested, since no hardware is available.

[ Where problems could occur ]

When using the old version of this driver, unpredictable kernel
crashes could potentially occur in certain situations.
