  "description": "In the Linux kernel, the following vulnerability has been resolved:  firmware: thead: Fix buffer overflow and use standard endian macros  Addresses two issues in the TH1520 AON firmware protocol driver:  1. Fix a potential buffer overflow where the code used unsafe pointer    arithmetic to access the \u0027mode\u0027 field through the \u0027resource\u0027 pointer    with an offset. This was flagged by Smatch static checker as:    \u0022buffer overflow \u0027data\u0027 2 \u003C= 3\u0022  2. Replace custom RPC_SET_BE* and RPC_GET_BE* macros with standard    kernel endianness conversion macros (cpu_to_be16, etc.) for better    portability and maintainability.  The functionality was re-tested with the GPU power-up sequence, confirming the GPU powers up correctly and the driver probes successfully.
