CVE-2026-90214
In the Linux kernel, the following vulnerability has been resolved: ASoC: xilinx: formatter_pcm: fix stream_data leak on open error In xlnx_formatter_pcm_open(), stream_data is allocated and adata->play_stream or adata->capture_stream is assigned early. If a later step, such as snd_pcm_hw_constraint_step() or snd_pcm_hw_constraint_integer(), fails, the function returns the error immediately. ALSA does not call the close callback when open fails, so stream_data is leaked and the stream pointer is left dangling, pointing to a substream that ALSA frees. A later interrupt would then call snd_pcm_period_elapsed() on the freed substream. Free stream_data and clear the stream pointer on the error paths.
