Bottlerocket: kernel-5.10, kernel-5.15: security update to 2.8.4

medium Tenable Cloud Security Plugin ID 427996

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 <ctrl-c> and starting it again this happens: |
