"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnull_blk: free global tag_set on init error path\n\nIf shared_tags is enabled, null_setup_tagset() allocates the global tag_set\nvia null_init_global_tag_set(). If device creation later fails, err_dev\ndestroys the default devices and calls unregister_blkdev(), but never frees\nthe global tag_set. Since module init failed, null_exit() is never invoked,\nso the global tag_set's tags and maps are permanently leaked.\n\nFree the global tag_set in err_dev, matching null_exit() which does\nif (tag_set.ops) blk_mq_free_tag_set(&tag_set)."
