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.

Original source description

Read the full publisher description

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

platform/x86: dell-wmi-base: Fix handling of ultra performance key

The commit message of commit 5fbd827eb9c2 ("platform/x86: dell-wmi: Recognise or support new switches") states that the ultra performance key contains additional data after the type and code fields. The event data passed to dell_wmi_process_key() is already parsed, so "buffer" already starts after those two fields.

Use the correct index for accessing the first data field to avoid a potential buffer overread.
