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