  "details": "In the Linux kernel, the following vulnerability has been resolved:  media: s2255: check firmware size before reading trailing marker  s2255_probe() reads a 4-byte marker and version from the last 8 bytes of the firmware blob (fw-\u003edata[fw_size - 8] and [fw_size - 4]). If the firmware file is shorter than 8 bytes, fw_size - 8 underflows and the access reads out of bounds. Validate the firmware size before indexing.",
