CVE-2026-64179
In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix potential memory leaks in ipc_imem_init() The memory allocated in ipc_protocol_init() is not freed on the error paths that follow in ipc_imem_init(). Fix that by calling the corresponding release function ipc_protocol_deinit() in the error path.
Executive briefing
The source record describes: In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix potential memory leaks in ipc_imem_init() The memory allocated in ipc_protocol_init() is not freed on the error paths that follow in ipc_imem_init(). Fix that by calling the corresponding release function ipc_protocol_deinit() in the error path. The practical risk depends on whether an affected product/version is present, reachable and configured in an exploitable way. Review the affected-product evidence and linked vendor advisories before assigning exposure status.
Evidence confidence: Moderate Evidence-derived, not an exploitability verdict
Severity & attack characteristics
CVSS vector:CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Technical explanation & impact
The technical mechanism is not expanded beyond the source description unless a referenced advisory supplies additional evidence. Read the linked vendor/CERT advisories for root-cause detail.
Potential impact must be interpreted from the published CVSS impact metrics and the affected component. A CVSS impact score is not proof that a particular asset is exploitable.
Weakness classification
CWE-401Affected products and versions
Products below are parsed from NVD vulnerable CPE configuration entries. Version boundaries are shown as published; verify applicability with the vendor.
| Vendor | Product | Version evidence |
|---|---|---|
| linux | linux_kernel | from (inclusive) 6.19; before 7.0.11 · CPE version 7.1 · CPE version 7.1 · CPE version 7.1 · CPE version 7.1 |
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
