+Subject: batman-adv: fix OOB read/write in network-coding decode
+
+From: Stanislav Fort <stanislav.fort@aisle.com>
+
+commit d77b6ff0ce35a6d0b0b7b9581bc3f76d041d4087 upstream.
+
+batadv_nc_skb_decode_packet() trusts coded_len and checks only against
+skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing
+payload headroom, and the source skb length is not verified, allowing an
+out-of-bounds read and a small out-of-bounds write.
+
+Validate that coded_len fits within the payload area of both destination
+and source sk_buffs before XORing.
+
+Fixes: 2df5278b0267 ("batman-adv: network coding - receive coded packets and decode them")

+From: Vitaly Lifshits <vitaly.lifshits@intel.com>
+
+commit 90fb7db49c6dbac961c6b8ebfd741141ffbc8545 upstream.
+
+Fix a possible heap overflow in e1000_set_eeprom function by adding
+input validation for the requested length of the change in the EEPROM.
+In addition, change the variable type from int to size_t for better
+code practices and rearrange declarations to RCT.

+Subject: scsi: lpfc: Fix buffer free/clear order in deferred receive path
+
+From: John Evans <evans1210144@gmail.com>
+
+commit 9dba9a45c348e8460da97c450cddf70b2056deb3 upstream.
+
+Fix a use-after-free window by correcting the buffer release sequence in
+the deferred receive path. The code freed the RQ buffer first and only
+then cleared the context pointer under the lock. Concurrent paths (e.g.,
+ABTS and the repost path) also inspect and release the same pointer under
+the lock, so the old order could lead to double-free/UAF.
+
+Note that the repost path already uses the correct pattern: detach the
+pointer under the lock, then free it after dropping the lock. The
+deferred path should do the same.

+Subject: wifi: mwifiex: Initialize the chan_stats array to zero
+
+From: Qianfeng Rong <rongqianfeng@vivo.com>
+
+commit 0e20450829ca3c1dbc2db536391537c57a40fe0b upstream.
+
+The adapter->chan_stats[] array is initialized in
+mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
+memory. The array is filled in mwifiex_update_chan_statistics()
+and then the user can query the data in mwifiex_cfg80211_dump_survey().
+
+There are two potential issues here. What if the user calls
+mwifiex_cfg80211_dump_survey() before the data has been filled in.
+Also the mwifiex_update_chan_statistics() function doesn't necessarily
+initialize the whole array. Since the array was not initialized at
+the start that could result in an information leak.
+
+Also this array is pretty small. It's a maximum of 900 bytes so it's
+more appropriate to use kcalloc() instead vmalloc().
