CVE-2026-80706

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: softing: fw_parse(): validate firmware record spans<br /> <br /> fw_parse() reads a fixed record header, a firmware-provided payload,<br /> and a trailing checksum without knowing the end of the firmware blob. A<br /> truncated record can therefore make those reads exceed the blob.<br /> <br /> The same record also supplies addresses and lengths for writes into<br /> DPRAM. The generic loader uses wrap-prone mixed signed arithmetic for its<br /> bounds check, while the application loader does not bound the staging<br /> copy at all.<br /> <br /> Pass the firmware end to the parser and validate the full source record.<br /> Use a signed wide offset for generic DPRAM records and validate the<br /> application staging span against the mapped DPRAM before copying.
