About this tag
The cve-2026-53339 tag covers a Linux kernel vulnerability affecting a specific Qualcomm CCI I2C driver path. The issue can trigger a kernel panic when a controller exposes two I2C masters but only one is initialized. Coverage is most relevant to Qualcomm-based Linux devices, embedded products, board-support teams, and testing of driver unload or device unbind paths. The recommended remediation is to install a fixed stable kernel or use a vendor kernel with the same fix backported for the relevant branch and board-support package. Ordinary desktops, generic x86 servers, and containers that do not run their own kernel are generally outside the primary risk described here.
