The \"null skcipher\" was being dropped when each af_alg_ctx was freed instead of when the aead_tfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user being able to crash the system or possibly escalate privileges."},{"lang":"es","value":"Se ha encontrado un error en el subsistema crypto del kernel de Linux en versiones anteriores a kernel-4.15-rc4. Se dejó \"null skcipher\" cuando se liberó cada af_alg_ctx en lugar de cuando se liberó aead_tfm.
