When\ndrmm_add_action() failed, the release function won't be added. As the\nresult, the ref cnt added by device_get() in drm_dev_init() won't be put\nby drm_dev_init_release(), which leads to the memleak. Use\ndrmm_add_action_or_reset() instead of drmm_add_action() to prevent\nmemleak.\n\nunreferenced object 0xffff88810bc0c800 (size 2048):\n  comm \"modprobe\", pid 8322, jiffies 4305809845 (age 15.292s)\n  hex dump (first 32 bytes):\n    e8 cc c0 0b 81 88 ff ff ff ff ff ff 00 00 00 00  ................\n    20 24 3c 0c 81 88 ff ff 18 c8 c0 0b 81 88 ff ff   $<.............\n  backtrace:\n    [<000000007251f72d>] __kmalloc+0x4b/0x1c0\n    [<0000000045f21f26>] platform_device_alloc+0x2d/0xe0\n    [<000000004452a479>] platform_device_register_full+0x24/0x1c0\n    [<0000000089f4ea61>] 0xffffffffa0736051\n    [<00000000235b2441>] do_one_initcall+0x7a/0x380\n    [<0000000001a4a177>] do_init_module+0x5c/0x230\n    [<000000002bf8a8e2>] load_module+0x227d/0x2420\n    [<00000000637d6d0a>] __do_sys_finit_module+0xd5/0x140\n    [<00000000c99fc324>] do_syscall_64+0x3f/0x90\n    [<000000004d85aa77>] entry_SYSCALL_64_after_hwframe+0x63/0xcd","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/07e56de8766fe5be67252596244b84ac0ec0de91","https://git.kernel.org/stable/c/bd8d1335e6e70a396094ef98913b513140c0b86b","https://git.kernel.org/stable/c/c47a823ea186263ab69cfb665327b7f72cb5e779","https://git.kernel.org/stable/c/ff963634f7b2e0dc011349abb3fb81a0d074f443"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2022-49830","score":0.00215,"percentile":0.11944,"date":"2026-10-31"},"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).
