What fixes it

  • 058f56de5f48ba4b3be01526006ac83ce9e79f39LinuxCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btintel: bound firmware ID by TLV length

The firmware ID is treated as a NUL-terminated string even though the TLV length is its only boundary. If the value does not contain a NUL terminator, snprintf() can read beyond the received response.

Limit the conversion to the advertised TLV value length.
