An issue was discovered in the Linux kernel before 6.0.11. Missing validation of IEEE80211_P2P_ATTR_CHANNEL_LIST in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger a heap-based buffer overflow when parsing the operating channel attribute from Wi-Fi management frames.

wifi: wilc1000: validate length of IEEE80211\_P2P\_ATTR\_CHANNEL\_LIST at…

…tribute

Validate that the IEEE80211\_P2P\_ATTR\_CHANNEL\_LIST attribute contains
enough space for a 'struct wilc\_attr\_oper\_ch'. If the attribute is too
small then it can trigger an out-of-bounds write later in the function.

'struct wilc\_attr\_oper\_ch' is variable sized so also check 'attr\_len'
does not extend beyond the end of 'buf'.

CVE-2022-47519: [PATCH 2/4] wifi: wilc1000: validate length of IEEE80211_P2P_ATTR_OPER_CHANNEL attribute

An issue was discovered in the Linux kernel before 6.0.11. Missing validation of the number of channels in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger a heap-based buffer overflow when copying the list of operating channels from Wi-Fi management frames.

Subject: \[PATCH 4/4\] wifi: wilc1000: validate number of channels
Date: Wed, 23 Nov 2022 10:35:43 -0500	\[thread overview\]
Message-ID: <20221123153543.8568-5-philipturnbull@github.com> (raw)
In-Reply-To: <20221123153543.8568-1-philipturnbull@github.com\>

There is no validation of 'e->no\_of\_channels' which can trigger an
out-of-bounds write in the following 'memset' call. Validate that the
number of channels does not extends beyond the size of the channel list
element.
