{"id":"CVE-2026-90214","summary":"ASoC: xilinx: formatter_pcm: fix stream_data leak on open error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: xilinx: formatter_pcm: fix stream_data leak on open error\n\nIn xlnx_formatter_pcm_open(), stream_data is allocated and\nadata-\u003eplay_stream or adata-\u003ecapture_stream is assigned early.  If a\nlater step, such as snd_pcm_hw_constraint_step() or\nsnd_pcm_hw_constraint_integer(), fails, the function returns the error\nimmediately.  ALSA does not call the close callback when open fails, so\nstream_data is leaked and the stream pointer is left dangling, pointing\nto a substream that ALSA frees.  A later interrupt would then call\nsnd_pcm_period_elapsed() on the freed substream.\n\nFree stream_data and clear the stream pointer on the error paths.","modified":"2026-09-19T03:47:25.412843856Z","published":"2026-09-17T16:07:27.407Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90214.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3fd89a51b8cfe788df67f54b716b305dd45b8468"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4e0ce77df7d9808926719d7950a07fbad14ea9ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e1a2d9fff57f3a2b1a0f54d128d64245a253004"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8b30628dfc2b2fad3b55a9441776a226035045fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c38ae4a465691947977c25d10394da22a64a19f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9030aa4e14b704dc39ee208207cb65064020d857"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b992511180e126150c6ad3580a6fd568c385f4c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edf81b293cba1b00a5e71becf184414f6991a6ca"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90214.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90214"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6f6c3c36f0917be24587eeba818ab4fdfcb5465a"},{"fixed":"5e1a2d9fff57f3a2b1a0f54d128d64245a253004"},{"fixed":"edf81b293cba1b00a5e71becf184414f6991a6ca"},{"fixed":"3fd89a51b8cfe788df67f54b716b305dd45b8468"},{"fixed":"8c38ae4a465691947977c25d10394da22a64a19f"},{"fixed":"9030aa4e14b704dc39ee208207cb65064020d857"},{"fixed":"8b30628dfc2b2fad3b55a9441776a226035045fa"},{"fixed":"4e0ce77df7d9808926719d7950a07fbad14ea9ef"},{"fixed":"b992511180e126150c6ad3580a6fd568c385f4c6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90214.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90214.json"}}],"schema_version":"1.9.0"}
