CVE-2026-23464 Details
Description
In the Linux kernel, the following vulnerability has been resolved: soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe() In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails, the function returns immediately without freeing the allocated memory for sys_controller, leading to a memory leak. Fix this by jumping to the out_free label to ensure the memory is properly freed. Also, consolidate the error handling for the mbox_request_channel() failure case to use the same label.
A memory leak vulnerability has been identified in the Linux kernel's handling of the Microchip MPFS system controller. The issue arises in the 'mpfs_sys_controller_probe()' function, where failure to retrieve the flash device node results in an immediate return without freeing the allocated memory for the system controller. This oversight creates a memory leak. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed in the Linux kernel stable tree. Users can upgrade to the latest version of the kernel to apply the fix.
