Hello, LinuxPatch customers! As part of our ongoing commitment to keep your systems secure, we've got an important update regarding a newly discovered vulnerability in the Linux kernel that demands your immediate attention. This issue, identified as CVE-2024-38627, has been classified with a high severity rating and a CVSS score of 7.8, indicating a substantial risk if left unaddressed.
What is CVE-2024-38627?
CVE-2024-38627 pertains to a critical flaw in the Linux kernel, specifically within the stm (Software Trace Macrocell) class. This class is utilized in Linux for helping with debugging and tracing complex software and system issues. The vulnerability stems from an error in the implementation called a double-free error in the 'stm_register_device()' function.
In technical terms, the function 'stm_register_device()' incorrectly executes a 'put_device(&stm->dev)' call that prematurely triggers 'stm_device_release()', which in turn prematurely frees the 'stm' memory object. Subsequently, the same 'stm' object is erroneously freed again by a 'vfree(stm)' call, leading to a double-free condition. Double free vulnerabilities can lead to system crashes, corrupt data, and potentially allow attackers to execute arbitrary code or escalate their privileges on affected systems.
Impact of CVE-2024-38627
The issue poses a significant threat because it affects the Linux kernel, which is at the heart of countless Linux distributions used in servers, desktops, and embedded devices across the globe. An attacker exploiting this fault can potentially gain unauthorized access or damage the system, leading to service disruptions and compromised data integrity and security.
