{"id":"CVE-2026-43301","summary":"media: chips-media: wave5: Fix PM runtime usage count underflow","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: chips-media: wave5: Fix PM runtime usage count underflow\n\nReplace pm_runtime_put_sync() with pm_runtime_dont_use_autosuspend() in\nthe remove path to properly pair with pm_runtime_use_autosuspend() from\nprobe. This allows pm_runtime_disable() to handle reference count cleanup\ncorrectly regardless of current suspend state.\n\nThe driver calls pm_runtime_put_sync() unconditionally in remove, but the\ndevice may already be suspended due to autosuspend configured in probe.\nWhen autosuspend has already suspended the device, the usage count is 0,\nand pm_runtime_put_sync() decrements it to -1.\n\nThis causes the following warning on module unload:\n\n  ------------[ cut here ]------------\n  WARNING: CPU: 1 PID: 963 at kernel/kthread.c:1430\n    kthread_destroy_worker+0x84/0x98\n  ...\n  vdec 30210000.video-codec: Runtime PM usage count underflow!","modified":"2026-07-08T08:13:29.414497585Z","published":"2026-05-08T13:11:22.234Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43301.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0bffda02317989f8d5cdc2d4462a4110b1290cf0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3a278a55ead50db2444c8f01410c7f5a68723990"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cf4452e824c1e2d41c9c0b13cc8a32a0a7dec38"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43301.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43301"},{"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":"9707a6254a8a6b978bde811a44fe07d86c229d1c"},{"fixed":"3a278a55ead50db2444c8f01410c7f5a68723990"},{"fixed":"0bffda02317989f8d5cdc2d4462a4110b1290cf0"},{"fixed":"9cf4452e824c1e2d41c9c0b13cc8a32a0a7dec38"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43301.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43301.json"}}],"schema_version":"1.7.5"}
