In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.
Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:
network={
ssid="somessid"
mode=2
frequency=2412
key_mgmt=WPA-PSK WPA-PSK-SHA256
proto=RSN
group=CCMP
pairwise=CCMP
psk="12345678"
}
When waiting for the AP to be established, interrupting wpa_supplicant
with and starting it again this happens:

CVE-2024-46755 [MEDIUM] CWE-476 GHSA-ch3p-mhx6-fjx9: In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
mwifiex_get
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.
Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:

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

Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
