Linux Kernel EUVD-2026-27618

Apply the vendor-released patch from the stable branch corresponding to your kernel version: kernel 6.6.136 or later, 6.12.83 or later, 6.18.24 or later, 6.19.14 or later, or 7.0 or later for mainline. The fix can be obtained from the Linux kernel stable repository at the commit hashes provided in references (dd5c49787a32da96a2b154427eb17cbf12a83c28, d8fdd6adc07b78ad3e9ee0004876d90cb59ca941, e352e9adc9f6df54d63150ff832f71c04e30744b, and 3eb7dd55021d0f4308fbea0bea21d2118984d8e7). Compile and install the patched kernel version for your system. If immediate patching is not possible, restrict local user access on systems with vc4 hardware acceleration or disable DRM vc4 driver support (if graphics are not required) via kernel configuration. Note that local user accounts are typically low-risk in production environments, mitigating real-world impact.
