In the Linux kernel, the following vulnerability has been resolved: crypto: algif_hash - fix double free in hash_accept If accept(2) is called on socket type algif_hash with MSG_MORE flag set and crypto_ahash_import fails, sk2 is freed. However, it is also freed in af_alg_release, leading to slab-use-after-free error.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: algif_hash - corrección de doble liberación en hash_accept. Si se ejecuta accept(2) en el socket tipo algif_hash con el indicador MSG_MORE activado y crypto_ahash_import falla, se libera sk2. Sin embargo, también se libera en af_alg_release, lo que genera un error de uso de slab después de la liberación.
