CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to trigger a use-after-free and double free.

The vulnerability exists due to a stale pointer after reallocation in meson_card_reallocate_links() when handling failure of the second memory reallocation after the first reallocation moves the DAI link array. A local user can cause the second memory reallocation to fail after the first reallocation moves the DAI link array to trigger a use-after-free and double free.
