Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mld: don't dereference a pointer before NULL checking it
In iwl_mld_remove_link, the link->fw_id is saved at the beginning of the
function so we have it after we freed the link.
But the link pointer can be NULL, and is not checked when the fw_id is
stored.
Fix it by simply freeing the link at the end of the function.
fFixes: 0e66a39f4f0e ("wifi: iwlwifi: fix potential use after free in iwl_mld_remove_link()")
Affected configurations
• linux linux kernel (< 6.18.34)
• linux linux kernel (>= 6.19 < 7.0.11)
