In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix node corruption in ar->arvifs list
In current WLAN recovery code flow, ath11k_core_halt() only
reinitializes the "arvifs" list head. This will cause the
list node immediately following the list head to become an
invalid list node. Because the prev of that node still points
to the list head "arvifs", but the next of the list head "arvifs"
no longer points to that list node.
When a WLAN recovery occurs during the execution of a vif
removal, and it happens before the spin_lock_bh(&ar->data_lock)
in ath11k_mac_op_remove_interface(), list_del() will detect the
previously mentioned situation, thereby triggering a kernel panic.
The fix is to remove and reinitialize all vif list nodes from the
list head "arvifs" during WLAN halt. The reinitialization is to make
the list nodes valid, ensuring that the list_del() in
ath11k_mac_op_remove_interface() can execute normally.

Impact
CVE-2025-38293 has a CVSS score of 5.5 (Medium). The vector is requires local access, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-38293? CVE-2025-38293 is a medium-severity security vulnerability. No fixed version is listed yet.
- How severe is CVE-2025-38293? CVE-2025-38293 has a CVSS score of 5.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Is there a fix for CVE-2025-38293? No fixed version is listed for CVE-2025-38293 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-38293 exploitable, and should I be worried? Whether CVE-2025-38293 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-38293 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
