In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix potential memory leaks in ipc_imem_init() The memory… (CVE-2026-64179)
A medium severity vulnerability in the Linux kernel's net: wwan: iosm component was fixed to address potential memory leaks in the ipc_imem_init() function. The issue involved allocated memory in ipc_protocol_init() not being freed on error paths, which could lead to resource exhaustion.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-64179) in the Linux kernel concerns a memory leak in the net: wwan: iosm subsystem. Specifically, memory allocated by ipc_protocol_init() was not properly released on error paths within ipc_imem_init(). The fix involves calling ipc_protocol_deinit() on these error paths to free the allocated memory, preventing leaks.
Potential Impact
This vulnerability can cause memory leaks leading to potential denial of service due to resource exhaustion. There is no impact on confidentiality or integrity, only availability is affected as indicated by the CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this memory leak by ensuring proper cleanup on error paths. Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the provided data; check the official Linux kernel advisories or vendor updates for the exact fixed versions and apply the update accordingly.
