CVE-2023-52530: Linux kernel Wi‑Fi driver could reuse a freed encryption key
CVE-2023-52530 · published 2 years ago
Summary
The Linux kernel's Wi‑Fi subsystem had a coding mistake that could cause it to keep using a security key after it had been released. While it is unlikely to affect most systems, it could allow an attacker to interfere with Wi‑Fi encryption. Update your Linux distribution to the latest kernel version, which includes the fix, or apply the vendor's security patches as soon as they are available.

Original advisory text
wifi: mac80211: fix potential key use-after-free
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix potential key use-after-free
When ieee80211_key_link() is called by ieee80211_gtk_rekey_add()
but returns 0 due to KRACK protection (identical key reinstall),
ieee80211_gtk_rekey_add() will still return a pointer into the
key, in a potential use-after-free. This normally doesn't happen
since it's only called by iwlwifi in case of WoWLAN rekey offload
which has its own KRACK protection, but still better to fix, do
that by returning an error code and converting that to success on
the cfg80211 boundary only, leaving the error for bad callers of
ieee80211_gtk_rekey_add().
