CVE-2026-90188: CVE-2026-90188: güvenlik açığı
Açıklama (NVD)
In the Linux kernel, the following vulnerability has been resolved: null_blk: free global tag_set on init error path If shared_tags is enabled, null_setup_tagset() allocates the global tag_set via null_init_global_tag_set(). If device creation later fails, err_dev destroys the default devices and calls unregister_blkdev(), but never frees the global tag_set. Since module init failed, null_exit() is never invoked, so the global tag_set's tags and maps are permanently leaked. Free the global tag_set in err_dev, matching null_exit() which does if (tag_set.ops) blk_mq_free_tag_set(&tag_set).
