Насколько мне известно, для эксплуатации уязвимости нужно:
1) worldwide-writable suid binary:
# l /usr/bin/su
-rws--x--- 1 root wheel 26920 сен 25 2024 /usr/bin/su
Наличие модуля algif_aead среди загруженных:
# lsmod | grep alg
algif_hash 12288 0
af_alg 36864 1 algif_hash
i2c_algo_bit 16384 2 xe,i915
