CVE-2026-99118 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/dmc: Harden DMC firmware payload parsing
Validate the conversion of the DMC firmware size from dwords to bytes
using check_mul_overflow() before calculating the firmware payload size.
Reject zero-length payloads and zero MMIO counts in the DMC firmware
header so malformed firmware is caught early. Also set dmc_fw_size only
after the payload allocation succeeds.
