The Linux kernel contained a vulnerability (CVE-2026-64179) in the net: wwan: iosm subsystem where memory allocated by ipc_protocol_init() was not properly freed if subsequent error conditions occurred in ipc_imem_init(). This could lead to potential memory leaks. The fix involved calling ipc_protocol_deinit() on error paths to release allocated memory, thereby resolving the leak.

The vulnerability could cause memory leaks in the Linux kernel's iosm component, potentially leading to resource exhaustion or degraded system performance. There is no indication of direct exploitation or other impacts such as code execution or privilege escalation.

A fix has been implemented in the Linux kernel to address this issue by properly freeing allocated memory on error paths. Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the provided data; therefore, check the official Linux kernel advisories for the exact fixed versions and apply updates accordingly.
