{"id":"AZL-73923","summary":"CVE-2025-38693 affecting package kernel for versions less than 5.15.200.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: dvb-frontends: w7090p: fix null-ptr-deref in w7090p_tuner_write_serpar and w7090p_tuner_read_serpar\n\nIn w7090p_tuner_write_serpar, msg is controlled by user. When msg[0].buf is null and msg[0].len is zero, former checks on msg[0].buf would be passed. If accessing msg[0].buf[2] without sanity check, null pointer deref would happen. We add\ncheck on msg[0].len to prevent crash.\n\nSimilar commit: commit 0ed554fd769a (\"media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()\")","modified":"2026-04-01T05:22:21.410215Z","published":"2025-09-04T16:15:37Z","upstream":["CVE-2025-38693"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38693"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73923.json"}}],"schema_version":"1.7.5"}
