CVE-2026-90214: ASoC: xilinx: formatter_pcm: fix stream_data leak on open error

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 3fd89a51b8cfe788df67f54b716b305dd45b8468, 4e0ce77df7d9808926719d7950a07fbad14ea9ef, 5e1a2d9fff57f3a2b1a0f54d128d64245a253004.

Low priority for now. Upgrade to Linux Linux 3fd89a51b8cfe788df67f54b716b305dd45b8468, 4e0ce77df7d9808926719d7950a07fbad14ea9ef, 5e1a2d9fff57f3a2b1a0f54d128d64245a253004 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
