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.
