Technical details
The vulnerability exists in the gf_odf_ac4_cfg_clean_list function in odf/descriptors.c, where improper pointer handling during linked list destruction leads to accessing freed memory. An attacker can trigger this by supplying a crafted AC4 audio file with malformed streams. The defect is in the recursive cleanup logic that does not properly manage node lifetime, allowing use-after-free conditions when processing nested or corrupt AC4 configuration lists.
