Vulnerability in Linux Kernel Affects Xilinx Audio Driver

CVE-2026-80743

What is CVE-2026-80743?

In the Linux kernel, an issue was identified in the Xilinx audio driver related to the handling of interrupt requests. The driver improperly sets the driver data during the probe sequence, which may lead to passing a NULL pointer to the readl() function during interrupts. This condition can potentially cause the system to crash when an interrupt occurs before the driver data is fully initialized. A fix has been implemented that passes the private data directly to the devm_request_irq() function, aligning with what the handlers expect and preventing the NULL pointer dereference.
