CVE-2026-93129
Published: September 19, 2026Last modified: October 23, 2026
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.
