Python Analisi e mitigazione delle vulnerabilità

CVE-2024-58065 is a security vulnerability discovered in the Linux kernel, specifically affecting the clock management subsystem (clk: mmp: pxa1908-apbc). The vulnerability was disclosed on March 6, 2025, and received its last modification on March 25, 2025. The issue stems from an incorrect error handling mechanism where the devm_kzalloc() function's return value was improperly checked, confusing NULL returns with error pointers (NVD).

The vulnerability is characterized by an improper NULL pointer versus IS_ERR() check in the PXA1908 APBC clock management code. It has been assigned a CVSS v3.1 base score of 5.5 (Medium severity) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The vulnerability requires local access and low privileges to exploit, with no user interaction needed. While it doesn't impact confidentiality or integrity, it can have a high impact on system availability (NVD).

The vulnerability's primary impact is on system availability, potentially leading to system crashes or denial of service conditions. The CVSS metrics indicate that while there is no impact on data confidentiality or integrity, the vulnerability can cause significant disruption to system operations when exploited (NVD).

The vulnerability has been patched in the Linux kernel. Two specific patches have been released to address this issue, available through the kernel's stable branch. The fix involves correcting the error checking logic for the devm_kzalloc() function return value (Kernel Patch, Kernel Patch).
