Action Type Old Value New Value Changed Description In the Linux kernel, the following vulnerability has been resolved: 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. Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. Removed Reference kernel.org: https://git.kernel.org/stable/c/de124365a7d2deed22cf706583930f28d537ff0f -
