{"id":"CVE-2026-68225","summary":"media: i2c: alvium: fix critical pointer access in alvium_ctrl_init","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: i2c: alvium: fix critical pointer access in alvium_ctrl_init\n\nThe current implementation of alvium_ctrl_init creates several controls in\nfunction alvium_ctrl_init and uses the returned pointer without check. That\ncan cause write access over NULL-pointer for several controls. The reworked\ncode checks the pointers before adding flags.","modified":"2026-08-18T03:31:02.816381540Z","published":"2026-08-10T12:00:47.085Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68225.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4bacfda44d36f165f6cb57bea408912886400ffa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4f6f28ff24709710c08557c127b3e4c3fb1b4159"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7337c88205ed0ffc654f40266be0d3c3eb15fb29"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb2f934646aefb06314cecd1deb020794829b207"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68225.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68225"},{"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":"0a7af872915ee34668edf7e4018648a226d9e7f9"},{"fixed":"4bacfda44d36f165f6cb57bea408912886400ffa"},{"fixed":"7337c88205ed0ffc654f40266be0d3c3eb15fb29"},{"fixed":"eb2f934646aefb06314cecd1deb020794829b207"},{"fixed":"4f6f28ff24709710c08557c127b3e4c3fb1b4159"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68225.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68225.json"}}],"schema_version":"1.9.0"}
