CVE-2026-80569

CVE-2026-80569 is a heap buffer overflow in the Linux kernel's synaptics-rmi4 input driver. The F54 diagnostics function allocates its report_data buffer based on F54 electrode counts, but computes the transfer size from F55 electrode counts. A malicious or malfunctioning RMI4 device that reports...

CVE-2026-80566

This Linux kernel vulnerability affects the hynitron_cstxxx input driver. The root cause is insufficient validation of touch count and finger IDs against the allocated input slot range before processing touch reports. An out-of-range finger ID or an oversized touch count can corrupt the touch sta...

CVE-2026-80558

This Linux kernel vulnerability affects the libceph subsystem. A corrupted osdmap received from a Ceph monitor or OSD may contain OSD indices in its primary_temp field that are greater than max_osd or smaller than CEPH_HOMELESS_OSD (-1). While most OSD indices in the osdmap are validated, the one...
