{"id":"CVE-2025-38694","summary":"media: dvb-frontends: dib7090p: fix null-ptr-deref in dib7090p_rw_on_apb()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: dvb-frontends: dib7090p: fix null-ptr-deref in dib7090p_rw_on_apb()\n\nIn dib7090p_rw_on_apb, msg is controlled by user. When msg[0].buf is null and\nmsg[0].len is zero, former checks on msg[0].buf would be passed. If accessing\nmsg[0].buf[2] without sanity check, null pointer deref would happen. We add\ncheck on msg[0].len to prevent crash. Similar issue occurs when access\nmsg[1].buf[0] and msg[1].buf[1].\n\nSimilar commit: commit 0ed554fd769a (\"media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()\")","modified":"2026-03-20T12:42:58.758829Z","published":"2025-09-04T15:32:47.449Z","related":["MGASA-2025-0234","MGASA-2025-0235","SUSE-SU-2025:03600-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38694.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09906650484a09b3a4d4b3d3065395856810becd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0bb32863426afe0badac25c28d59021f211d0f48"},{"type":"WEB","url":"https://git.kernel.org/stable/c/19eb5d8e6aa1169d368a4d69aae5572950deb89d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/529fd5593b721e6f4370c591f5086649ed149ff6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a0f744d6cdde81d7382e183f77a4080a39b206cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc07cae4f36bb18d5b6a9ed835c1278ca44ec82e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c33280d6bd668dbdc5a5f07887cc63a52ab4789c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce5cac69b2edac3e3246fee03e8f4c2a1075238b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce8b7c711b9c4f040b5419729d0972db8e374324"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38694.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38694"},{"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":"713d54a8bd812229410a1902cd9b332a2a27af9f"},{"fixed":"bc07cae4f36bb18d5b6a9ed835c1278ca44ec82e"},{"fixed":"ce8b7c711b9c4f040b5419729d0972db8e374324"},{"fixed":"529fd5593b721e6f4370c591f5086649ed149ff6"},{"fixed":"c33280d6bd668dbdc5a5f07887cc63a52ab4789c"},{"fixed":"09906650484a09b3a4d4b3d3065395856810becd"},{"fixed":"0bb32863426afe0badac25c28d59021f211d0f48"},{"fixed":"a0f744d6cdde81d7382e183f77a4080a39b206cd"},{"fixed":"19eb5d8e6aa1169d368a4d69aae5572950deb89d"},{"fixed":"ce5cac69b2edac3e3246fee03e8f4c2a1075238b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38694.json"}}],"schema_version":"1.7.5"}
