CVE-2026-74451 in Linux
Summary
by MITRE • 08/15/2026
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: validate firmware interface structure sizes
iface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual address points inside the shared section. The returned pointer is later used as a full firmware interface structure, so accepting an address near the end of the shared section can still lead to out-of-bounds accesses.
Pass the expected object size to iface_fw_to_cpu_addr() and reject ranges that do not fit entirely in the shared section.
