CVE-2026-80759: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_aml: validate firmware segment lengths aml_download_firmware() reads two lengths from the firmware header and uses them to build pointers before checking that the header and segment data are present. A truncated or inconsistent firmware image can make the driver read past firmware->data while constructing TCI commands. Reject images shorter than the header and ensure that the ICCM and DCCM ranges fit within the loaded firmware before downloading either segment.

Affected products

• Linux Linux: from 6.12, before 6.12.106 (fixed in 6.12.106); from 6.13, before 6.18.47 (fixed in 6.18.47); from 6.19, before 7.1.11 (fixed in 7.1.11); from 7.2, before 7.2.1 (fixed in 7.2.1)
