In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: fix stream context array leak in cdnsp_alloc_stream_info()… (CVE-2026-64350)
A vulnerability in the Linux kernel's usb cdnsp driver was fixed to address a memory leak issue. The function cdnsp_alloc_stream_info() improperly handled error paths by not freeing the allocated stream context array, leading to a resource leak. This issue was resolved by ensuring the stream context array is freed during error cleanup.
AI Analysis
Technical Summary
The Linux kernel's usb cdnsp driver contained a vulnerability where the function cdnsp_alloc_stream_info() allocated a stream context array but failed to free it if subsequent allocations or updates failed. Specifically, if the stream ring allocation or stream mapping update failed, the error handling code freed some resources but left the stream context array allocated, causing a memory leak. The fix involved freeing the stream context array before proceeding with the cleanup of stream rings, preventing the leak.
Potential Impact
The vulnerability causes a memory leak in the Linux kernel's usb cdnsp driver during certain error conditions. While this does not directly lead to code execution or privilege escalation, memory leaks can degrade system stability or lead to denial of service over time if exploited repeatedly.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users should update to the fixed kernel version once available. Patch status is not yet confirmed in this data; check the official Linux kernel advisories or vendor updates for the exact fixed versions and apply the official patch accordingly.
