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.

CVE-2026-93110

A high‑severity flaw in the Linux kernel’s RDMA core module allows a use‑after‑free condition when a module is unloaded while RCU callbacks are still queued. The bug can cause kernel crashes or, in the worst case, arbitrary code execution if an attacker can trigger the callback after the module is gone.
