{"id":"CVE-2026-89896","summary":"media: cedrus: fix memory leak in cedrus_init_ctrls()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: cedrus: fix memory leak in cedrus_init_ctrls()\n\nIn cedrus_init_ctrls(), the V4L2 control handler is initialized before\nallocating memory for ctx-\u003ectrls. If this allocation fails, the function\nreturns -ENOMEM without freeing the previously allocated handler\nresources, leading to a memory leak.\n\nFix this by calling v4l2_ctrl_handler_free() on the ctx-\u003ectrls allocation\nfailure path.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1.1.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have an\nAllwinner SoC or board with a Cedrus VPU available to test with, no\nruntime testing was able to be performed.","modified":"2026-09-18T03:48:33.629266120Z","published":"2026-09-16T10:31:57.504Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89896.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/22441be29ec27c693f40c1ef499093275ef529d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6fabacc3b79a528450aef4c32464da2ec681049e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/729a1ffab968b3c493f61d1cd683f5bafec500ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79fd0b0161506fc9507bf7a6fe4c975a857a5be8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81aa608ac3a56cdd4aab0bd12442ed529a24ba31"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9df2fbe563194da1967a5db083442186c1323efe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce5693b6e3a693fcdc3800af309363f6250104c8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f78cf36cabf911da348ea80e4e9f430d74f6905c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89896.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89896"},{"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":"50e761516f2b8c0cdeb31a8c6ca1b4ef98cd13f1"},{"fixed":"6fabacc3b79a528450aef4c32464da2ec681049e"},{"fixed":"729a1ffab968b3c493f61d1cd683f5bafec500ea"},{"fixed":"ce5693b6e3a693fcdc3800af309363f6250104c8"},{"fixed":"22441be29ec27c693f40c1ef499093275ef529d1"},{"fixed":"79fd0b0161506fc9507bf7a6fe4c975a857a5be8"},{"fixed":"f78cf36cabf911da348ea80e4e9f430d74f6905c"},{"fixed":"81aa608ac3a56cdd4aab0bd12442ed529a24ba31"},{"fixed":"9df2fbe563194da1967a5db083442186c1323efe"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89896.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89896.json"}}],"schema_version":"1.9.0"}
