Kernel memory disclosure via unchecked enum index
Published Aug 15, 2026 · Updated Aug 15, 2026
Out-of-bounds read in Linux kernel ASoC SDCA 7.0 allows local users to disclose kernel memory through a crafted enum control write. The ge_put_enum_double() handler passes an unchecked item[0] index to snd_soc_enum_item_to_val(), which reads beyond the heap-allocated e->values[] array before a later bounds check runs. A low-privileged local user with access to the affected ASoC SDCA control can disclose adjacent kernel memory or crash the system.
