"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfwctl: pds: Validate RPC input size before parsing\n\nThe fwctl core allocates the device-specific RPC input buffer with\nfwctl_rpc.in_len and passes that buffer to the driver callback.\n\npdsfc_fw_rpc() casts the buffer to struct fwctl_rpc_pds and then calls\npdsfc_validate_rpc(), which reads fields from that structure before\nchecking that the input buffer is large enough to contain it. A short\nin_len can make pds_fwctl read beyond the allocation.\n\nReject pds RPC buffers that are smaller than struct fwctl_rpc_pds before\nparsing any pds-specific fields."
