A memory corruption vulnerability in the Linux kernel's imx_sc_key component was identified and resolved. The issue was caused by passing the address of a stack variable instead of the variable itself, leading to memory corruption when the imx_sc_key_action() function was called. This vulnerability has been fixed in the Linux kernel source. The flaw could allow an attacker with local privileges to cause confidentiality, integrity, and availability impacts.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel's imx_sc_key driver involved incorrect handling of a pointer argument, where the address of a stack variable ('&priv') was passed instead of the variable itself ('priv'). This led to memory corruption during execution of the imx_sc_key_action() function. The issue has been corrected by removing the erroneous address operator. The CVSS 3.1 vector indicates the attack requires local access with low complexity and privileges, no user interaction, and results in high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could lead to memory corruption, potentially allowing an attacker with local access and low privileges to compromise system confidentiality, integrity, and availability. This could result in arbitrary code execution or system instability.
Mitigation Recommendations
A fix has been implemented in the Linux kernel source code to correct the pointer usage in the imx_sc_key driver. Users and administrators should apply the official Linux kernel updates that include this fix once available. Patch status is not yet confirmed in this data; check the vendor advisory for current remediation guidance.
