CVE-2026-23464
Description
A flaw was found in the Linux kernel, specifically within the Microchip PolarFire SoC (System-on-Chip) system controller driver. When the mpfs_sys_controller_probe() function fails to initialize a device, it does not properly release allocated memory. This memory leak can accumulate over time, potentially leading to system instability or a denial of service (DoS) condition, where legitimate system operations are disrupted.
