kernel update

This kernel update tag covers a Qualcomm Linux kernel panic vulnerability tracked as CVE-2026-53339. The issue affects systems using the vulnerable Qualcomm CCI I2C driver path when hardware exposes two I2C masters but initializes only one. The recommended response is to install a fixed stable kernel or use a vendor kernel that backports the correction for the relevant branch and board support package. The risk is most relevant to Qualcomm-based Linux devices, embedded products, and board-support teams, as well as testing involving driver unload or device unbind paths. Ordinary desktops, generic x86 servers, and containers that do not run their own kernel are generally outside the broad impact described here.
