This caused a resource leak.\n\nFix it by introducing a proper err_m2m_ctx_release label\nthat calls v4l2_m2m_ctx_release(sess->m2m_ctx) before\nreleasing the m2m device.\n\nThis was identified via kmemleak:\nunreferenced object 0xffff0000205d6878 (size 8):\n  comm \"v4l_id\", pid 5289, jiffies 4294938580\n  hex dump (first 8 bytes):\n    40 d2 49 18 00 00 ff ff                          @.I.....\n  backtrace (crc d3204599):\n    kmemleak_alloc+0xc8/0xf0\n    __kvmalloc_node_noprof+0x60c/0x850\n    v4l2_ctrl_handler_init_class+0x1b4/0x2e8 [videodev]\n    vdec_open+0x1f4/0x788 [meson_vdec]\n    v4l2_open+0x144/0x460 [videodev]\n    chrdev_open+0x1ac/0x500\n    do_dentry_open+0x3f0/0xfe8\n    vfs_open+0x68/0x320\n    do_open+0x2d8/0x9a8\n    path_openat+0x1d0/0x4f0\n    do_filp_open+0x190/0x380\n    do_sys_openat2+0xf8/0x1b0\n    __arm64_sys_openat+0x13c/0x1e8\n    invoke_syscall+0xdc/0x268\n    el0_svc_common.constprop.0+0x178/0x258\n    do_el0_svc+0x4c/0x70","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1391b75bf0119b5d37f1c1c3078d452a01967f9b","https://git.kernel.org/stable/c/2cf0171ad594860e31723c671e37824ce12c01ea","https://git.kernel.org/stable/c/5f97120d1a50c9efffe54425fac42bb7ef13ac86","https://git.kernel.org/stable/c/940f161f734b25f175a95d2684c2021f6323693a","https://git.kernel.org/stable/c/99f3527bd1a27ff798d59177ed045b0dd87deaef"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68223","score":0.0022,"percentile":0.12569,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
