In the Linux kernel, the following vulnerability has been resolved: platform/x86: intel: punit_ipc: fix memory corruption This passes the address of… (CVE-2025-68303)
A memory corruption vulnerability in the Linux kernel's platform/x86 Intel punit_ipc component has been resolved. The issue was caused by passing the address of a pointer instead of the pointer itself, leading to writes to incorrect memory locations. This flaw could result in high impact on confidentiality, integrity, and availability of the affected system.
AI Analysis
Technical Summary
CVE-2025-68303 is a vulnerability in the Linux kernel's platform/x86 Intel punit_ipc driver where the code mistakenly passes the address of the pointer "&punit_ipcdev" instead of the pointer "punit_ipcdev" itself. This causes the function complete(&ipcdev->cmd_complete) in intel_punit_ioc() to write to an incorrect memory address, resulting in memory corruption. The vulnerability has been resolved in the Linux kernel. The CVSS 3.1 vector indicates local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this vulnerability could lead to memory corruption, which may allow an attacker with local access and low privileges to compromise system confidentiality, integrity, and availability. This could result in system crashes, data corruption, or potential privilege escalation depending on the exploitation context.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should update their Linux kernel to the latest patched version that includes this fix. Since this is a kernel-level vulnerability, applying the official kernel update is the recommended remediation. No additional mitigations are specified.
