CVE-2024-46849 is a use-after-free vulnerability in the Linux kernel's ASoC meson axg-card driver. The flaw involves improper handling of the 'card->dai_link' buffer, which is reallocated without correctly updating the 'pad' pointer, leading to a use-after-free condition. This issue has been fixed by moving the 'pad' pointer initialization after the reallocation function. The vulnerability has a high severity score of 7.8 and affects kernel versions prior to the fix.
