| Description | 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->data[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. |
