Detailsinfo

A vulnerability was found in Linux Kernel up to 6.15.9/6.16.0. It has been declared as problematic. The CWE definition for the vulnerability is CWE-617. The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix WARN_ON for monitor mode on some devices On devices without WANT_MONITOR_VIF (and probably without channel context support) we get a WARN_ON for changing the per-link setting of a monitor interface. Since we already skip AP_VLAN interfaces and MONITOR with WANT_MONITOR_VIF and/or NO_VIRTUAL_MONITOR should update the settings, catch this in the link change code instead of the warning.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2025-38642 since 04/16/2025. There are neither technical details nor an exploit publicly available.
