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","epss":{"date":"2026-11-05","percentile":0.12,"score":0.00215},"exploits":[],"kev":null,"metrics":[],"modifiedAt":1793908808847,"publishedAt":1746108588918,"references":[{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/c47a823ea186263ab69cfb665327b7f72cb5e779"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/07e56de8766fe5be67252596244b84ac0ec0de91"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/bd8d1335e6e70a396094ef98913b513140c0b86b"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/ff963634f7b2e0dc011349abb3fb81a0d074f443"}],"remediation":[],"revision":"d433f6ca6193c92fd3ad031a67e848f1f5aa98d64e785927bf5972086fa08fd4","sources":[{"modifiedAt":1793908808847,"name":"CNA: Linux","retrievedAt":1793909461517,"url":"https://www.cve.org/CVERecord?id=CVE-2022-49830"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793909486258,"url":"https://api.first.org/data/v1/epss?cve=CVE-2022-49830"}],"ssvc":{"assessedAt":1793908217817,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"drm/drv: Fix potential memory leak in drm_dev_init()","updatedAt":1793909486258}
