CVE-2024-53076

Local denial of service via allocation error leak

Published Nov 19, 2024 · Updated Aug 5, 2026

Memory leak in Linux kernel 6.4 allows local users to exhaust memory and interrupt service through a faulty allocation error path. In iio_gts_build_avail_scale_table(), the err_free_out loop stops before index zero and leaves per_time_scales[0] and per_time_gains[0] allocated. Reachability requires local low-privileged access and execution of the IIO gain-time-scale table builder while a per-time allocation fails.
