  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: hda: Fix missing pointer check in hda_component_manager_init function\n\nThe __component_match_add function may assign the 'matchptr' pointer\nthe value ERR_PTR(-ENOMEM), which will subsequently be dereferenced.\n\nThe call stack leading to the error looks like this:\n\nhda_component_manager_init\n|-> component_match_add\n    |-> component_match_add_release\n        |-> __component_match_add ( ... ,**matchptr, ... )\n            |-> *matchptr = ERR_PTR(-ENOMEM);       // assign\n|-> component_master_add_with_match( ...  match)\n    |-> component_match_realloc(match, match->num); // dereference\n\nAdd IS_ERR() check to prevent the crash.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.",
