Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

cve.new guidance unless attributed to a publisher. This page does not inspect your installation.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher description

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

Bluetooth: btintel: fix buffer over-read in btintel_hw_error()

The "Exception info %s" print uses skb->data + 1, but the 12-byte payload is not guaranteed to be NUL-terminated and can be read past its end.

Bound the print with "%.*s" and skb->len - 1.
