In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: rtl8192du: Fix possible memory leak in rtl92du_init_sw_vars() The… (CVE-2026-80942)
A memory leak vulnerability in the Linux kernel's rtlwifi driver for rtl8192du devices has been fixed. The issue was due to allocated memory inside rtl92du_init_shared_data() not being freed on error paths in rtl92du_init_sw_vars(). The fix adds a call to rtl92du_deinit_shared_data() to properly free memory on error.
AI Analysis
Technical Summary
The Linux kernel rtlwifi driver for rtl8192du devices contained a memory leak vulnerability where memory allocated in rtl92du_init_shared_data() was not freed if an error occurred in rtl92du_init_sw_vars(). This could lead to resource exhaustion over time. The vulnerability was resolved by adding a call to rtl92du_deinit_shared_data() in the error handling path to ensure proper cleanup of allocated memory.
Potential Impact
The vulnerability could cause a memory leak in the kernel's wifi driver, potentially leading to increased memory usage and resource exhaustion on affected systems. There is no indication of direct code execution or privilege escalation from this issue.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this memory leak by ensuring allocated memory is freed on error paths. Users should update to the fixed kernel version containing this patch once available. Patch status is not explicitly confirmed; check the vendor advisory or Linux kernel mailing lists for the specific fixed version.
