-Subject: [PATCH] wifi: cfg80211: fix u8 overflow in
- cfg80211_update_notlisted_nontrans()
-
-commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.
-
-In the copy code of the elements, we do the following calculation
-to reach the end of the MBSSID element:
-
- /* copy the IEs after MBSSID */
- cpy_len = mbssid[1] + 2;
-
-This looks fine, however, cpy_len is a u8, the same as mbssid[1],
-so the addition of two can overflow. In this case the subsequent
-memcpy() will overflow the allocated buffer, since it copies 256
-bytes too much due to the way the allocation and memcpy() sizes
-are calculated.
-
-Fix this by using size_t for the cpy_len variable.
-
-This fixes CVE-2022-41674.

-Subject: [PATCH] mac80211: mlme: find auth challenge directly
-
-commit 49a765d6785e99157ff5091cc37485732496864e upstream.
-
-There's no need to parse all elements etc. just to find the
-authentication challenge - use cfg80211_find_elem() instead.
-This also allows us to remove WLAN_EID_CHALLENGE handling
-from the element parsing entirely.

-Subject: [PATCH] mac80211: always allocate struct ieee802_11_elems
-
-As the 802.11 spec evolves, we need to parse more and more
-elements. This is causing the struct to grow, and we can no
-longer get away with putting it on the stack.
-
-Change the API to always dynamically allocate and return an
-allocated pointer that must be kfree()d later.
-
-As an alternative, I contemplated a scheme whereby we'd say
-in the code which elements we needed, e.g.
-
- DECLARE_ELEMENT_PARSER(elems,
- SUPPORTED_CHANNELS,
- CHANNEL_SWITCH,
- EXT(KEY_DELIVERY));
-
- ieee802_11_parse_elems(..., &elems, ...);
-
-and while I think this is possible and will save us a lot
-since most individual places only care about a small subset
-of the elements, it ended up being a bit more work since a
-lot of places do the parsing and then pass the struct to
-other functions, sometimes with multiple levels.

-Subject: [PATCH] wifi: mac80211: fix MBSSID parsing use-after-free
-
-commit ff05d4b45dd89b922578dac497dcabf57cf771c6
-
-When we parse a multi-BSSID element, we might point some
-element pointers into the allocated nontransmitted_profile.
-However, we free this before returning, causing UAF when the
-relevant pointers in the parsed elements are accessed.
-
-Fix this by not allocating the scratch buffer separately but
-as part of the returned structure instead, that way, there
-are no lifetime issues with it.
-
-The scratch buffer introduction as part of the returned data
-here is taken from MLO feature work done by Ilan.
-
-This fixes CVE-2022-42719.
-
-Fixes: 5023b14cf4df ("mac80211: support profile split between elements")

-Subject: [PATCH] wifi: cfg80211/mac80211: reject bad MBSSID elements
-
-commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.
-
-Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
-and the minimum is 1 since a multiple BSSID set with just one BSSID
-doesn't make sense (the # of BSSIDs is limited by 2^n).
-
-Limit this in the parsing in both cfg80211 and mac80211, rejecting
-any elements with an invalid value.
-
-This fixes potentially bad shifts in the processing of these inside
-the cfg80211_gen_new_bssid() function later.
-
-I found this during the investigation of CVE-2022-41674 fixed by the
-previous patch.
-
-Fixes: 0b8fb8235be8 ("cfg80211: Parsing of Multiple BSSID information in scanning")
-Fixes: 78ac51f81532 ("mac80211: support multi-bssid")

-Subject: [PATCH] wifi: cfg80211: fix BSS refcounting bugs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=utf8
-Content-Transfer-Encoding: 8bit
-
-commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.
-
-There are multiple refcounting bugs related to multi-BSSID:
- - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
- the bss pointer is overwritten before checking for the
- transmitted BSS, which is clearly wrong. Fix this by using
- the bss_from_pub() macro.
-
- - In cfg80211_bss_update() we copy the transmitted_bss pointer
- from tmp into new, but then if we release new, we'll unref
- it erroneously. We already set the pointer and ref it, but
- need to NULL it since it was copied from the tmp data.
-
- - In cfg80211_inform_single_bss_data(), if adding to the non-
- transmitted list fails, we unlink the BSS and yet still we
- return it, but this results in returning an entry without
- a reference. We shouldn't return it anyway if it was broken
- enough to not get added there.
-
-This fixes CVE-2022-42720.

-Content-Transfer-Encoding: 8bit
-
-commit bcca852027e5878aec911a347407ecc88d6fff7f upstream.
-
-If a non-transmitted BSS shares enough information (both
-SSID and BSSID!) with another non-transmitted BSS of a
-different AP, then we can find and update it, and then
-try to add it to the non-transmitted BSS list. We do a
-search for it on the transmitted BSS, but if it's not
-there (but belongs to another transmitted BSS), the list
-gets corrupted.
-
-Since this is an erroneous situation, simply fail the
-list insertion in this case and free the non-transmitted
-BSS.

-This fixes CVE-2022-42721.

-commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.
-
-When updating beacon elements in a non-transmitted BSS,
-also update the hidden sub-entries to the same beacon
-elements, so that a future update through other paths
-won't trigger a WARN_ON().
-
-The warning is triggered because the beacon elements in
-the hidden BSSes that are children of the BSS should
-always be the same as in the parent.

-Subject: [PATCH] mac80211: mesh: clean up rx_bcn_presp API
-
-commit a5b983c6073140b624f64e79fea6d33c3e4315a0 upstream.
-
-We currently pass the entire elements to the rx_bcn_presp()
-method, but only need mesh_config. Additionally, we use the
-length of the elements to calculate back the entire frame's
-length, but that's confusing - just pass the length of the
-frame instead.
