Understanding the Impact of CVE-2023-52457 on Linux Kernel

Hello LinuxPatch Customers,

In our commitment to keep you informed and secure, we're shedding light on a recent high-severity vulnerability identified within the Linux kernel. Known as CVE-2023-52457, this issue has been given a CVSS score of 7.8, indicating a significant risk that requires immediate attention.

What is CVE-2023-52457?

This vulnerability centers around incorrect handling of certain resources in the Linux kernel, specifically within the serial 8250 driver on OMAP (Open Multimedia Applications Platform) hardware. The primary concern is the potential for a used-after-free error, which occurs when the driver fails to properly free resources during a failure in the pm_runtime_resume_and_get() function. Such a condition not only causes a resource leak but may also allow an attacker to exploit this state to execute arbitrary code with kernel privileges.

How Does This Affect Your System?

This vulnerability specifically impacts systems that use OMAP-based serial ports managed by the 8250 driver. If your system or devices rely on this technology for serial communication, it's crucial to address this vulnerability promptly to prevent potential exploitation. The use-after-free condition could lead to system instability, information leakage, or even give attackers a foothold to further compromise the system.
