Detailsinfo

A vulnerability, which was classified as critical, was found in Sony XAV-AX5500 (the affected version unknown). Affected is an unknown part of the component CarPlay TLV. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Sony XAV-AX5500 CarPlay TLV Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-AX5500 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the Apple CarPlay protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23238
