CVE-2026-98673

A flaw was found in the Linux kernel's PAC1934 driver. This vulnerability can result in a Denial of Service (DoS) due to a kernel crash caused by an invalid memory access. When the driver processes device configuration labels from the ACPI (Advanced Configuration and Power Interface) firmware tables, it does not verify whether memory allocation succeeded before attempting to write to the label buffer. Under memory-constrained conditions during device initialization, this missing check triggers a crash that halts the system.
