{"id":"CVE-2023-53146","summary":"media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()\n\nIn dw2102_i2c_transfer, msg is controlled by user. When msg[i].buf\nis null and msg[i].len is zero, former checks on msg[i].buf would be\npassed. Malicious data finally reach dw2102_i2c_transfer. If accessing\nmsg[i].buf[0] without sanity check, null ptr deref would happen.\nWe add check on msg[i].len to prevent crash.\n\nSimilar commit:\ncommit 950e252cb469\n(\"[media] dw2102: limit messages to buffer size\")","modified":"2026-04-11T12:46:41.974169Z","published":"2025-05-14T12:43:59.117Z","related":["SUSE-SU-2025:01964-1","SUSE-SU-2025:01965-1","SUSE-SU-2025:02000-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20408-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20419-1","SUSE-SU-2025:20421-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53146.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/08dfcbd03b2b7f918c4f87c6ff637054e510df74"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ae544d94abc8ff77b1b9bf8774def3fa5689b5b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77cbd42d29de9ffc93d5529bab8813cde53af14c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/903566208ae6bb9c0e7e54355ce75bf6cf72485d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/97fdbdb750342cbc204befde976872fedb406ee6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/beb9550494e7349f92b9eaa283256a5ad9b1c9be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecbe6d011b95c7da59f014f8d26cb7245ed1e11e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb28afab113a82b89ffec48c8155ec05b4f8cb5e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53146.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53146"},{"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":"7fd4828f6cc5bd4339ff58e372ccb5f528548b30"},{"fixed":"77cbd42d29de9ffc93d5529bab8813cde53af14c"},{"fixed":"ecbe6d011b95c7da59f014f8d26cb7245ed1e11e"},{"fixed":"beb9550494e7349f92b9eaa283256a5ad9b1c9be"},{"fixed":"97fdbdb750342cbc204befde976872fedb406ee6"},{"fixed":"903566208ae6bb9c0e7e54355ce75bf6cf72485d"},{"fixed":"08dfcbd03b2b7f918c4f87c6ff637054e510df74"},{"fixed":"fb28afab113a82b89ffec48c8155ec05b4f8cb5e"},{"fixed":"5ae544d94abc8ff77b1b9bf8774def3fa5689b5b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53146.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.27"},{"fixed":"4.14.326"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.295"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.257"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.197"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.133"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.5.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53146.json"}}],"schema_version":"1.7.5"}
