CVE-2026-53285

The CVE-2026-53285 issue concerns the Linux kernel drm/amd/display path, where dcn32_enable_phantom_plane() allocates ~335 KiB via kvzalloc() within an FPU-enabled, softirq-disabled region. This vmalloc flow can trigger BUG_ON(in_interrupt()), causing a kernel crash (DoS). The root cause is the l...
