{"id":"AZL-102305","summary":"CVE-2026-90214 affecting package kernel 6.6.150.1-1","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":"2026-09-18T14:17:50.151732316Z","published":"2026-09-17T17:17:16Z","upstream":["CVE-2026-90214"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90214"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102305.json"}}],"schema_version":"1.9.0"}
