CVE-2023-53028

Summary

CVE-2023-53028 involves a memory leak issue in the Linux kernel that was resolved by reverting a commit related to the mac80211 driver. The vulnerability was reported to cause a null pointer dereference, potentially leading to a kernel crash, as evidenced by a stack trace and a hardware report from Google Compute Engine. This issue arose due to the fact that ieee80211_if_free() was already called when freeing a network device, causing the memory leak to go unaddressed. The vulnerability could potentially be exploited by an attacker to execute arbitrary code on the affected system.
