CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's fwctl component, where insufficient validation of the Remote Procedure Call (RPC) input size can lead to buffer overflows. This flaw allows attackers to exploit the system by causing the kernel to read beyond allocated memory, potentially leading to arbitrary code execution or system crashes. Organizations using Linux systems, particularly those relying on fwctl for device management, should prioritize addressing this vulnerability to mitigate associated risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: fwctl: pds: Validate RPC input size before parsing The fwctl core allocates the device-specific RPC input buffer with fwctl_rpc.in_len and passes that buffer to the driver callback. pdsfc_fw_rpc() casts the buffer to struct fwctl_rpc_pds and then calls pdsfc_validate_rpc(), which reads fields from that structure before checking that the input buffer is large enough to contain it. A short in_len can make pds_fwctl read beyond the allocation. Reject pds RPC buffers that are smaller than struct fwctl_rpc_pds before parsing any pds-specific fields.
