About this tag
The socketcan tag on WindowsForum.com covers discussions about the Linux SocketCAN subsystem, a set of open-source CAN protocol drivers and a networking stack for Controller Area Network (CAN) hardware. Recent threads focus on kernel vulnerabilities in SocketCAN components, including a deadlock in the mcp251x driver (CVE-2026-23357) and an out-of-bounds access in the CAN gateway CRC8 checksum code (CVE-2026-31570). These threads provide technical analysis, patch guidance, and workarounds for Linux kernel security issues affecting SocketCAN users. The tag is relevant for Linux system administrators, embedded developers, and security researchers working with CAN bus interfaces on Linux.

  1. CVE-2026-23357: Linux mcp251x Deadlock Lets Kernel Availability Hang

    CVE-2026-23357 is a Linux kernel vulnerability in the SocketCAN mcp251x driver, a driver used for Microchip MCP251x and MCP25625 SPI-based CAN controllers. The issue is a deadlock in the error-handling path of mcp251x_open(), specifically involving free_irq() being called while the driver’s...
