CVE-2026-64350 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: fix stream context array leak in cdnsp_alloc_stream_info() cdnsp_alloc_stream_info() allocates stream_info->stream_ctx_array with cdnsp_alloc_stream_ctx(). If a later stream ring allocation or stream mapping update fails, the error path frees the allocated stream rings and stream_rings array, but leaves stream_ctx_array allocated. Free the stream context array before falling through to the stream_rings cleanup path.
A memory leak vulnerability has been identified in the Linux kernel's USB Cadence driver, specifically within the function 'cdnsp_alloc_stream_info()'. This function allocates a stream context array but fails to properly free it if subsequent operations, such as stream ring allocation or mapping updates, encounter errors. As a result, the allocated stream context array remains in memory, leading to a resource leak. The issue arises in versions of the Linux kernel that include the Cadence USBSSP DRD driver.
The vulnerability has been addressed in the Linux kernel stable tree. Users can apply the latest updates from the Linux kernel stable repository to mitigate this issue.
