In the Linux kernel, the following vulnerability has been resolved: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() xattr in ocfs2 maybe 'non-indexed', which saved with additional space requested. It's better to check if the memory is out of bound before memcmp, although this possibility mainly comes from crafted poisonous images.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ocfs2: verificación de límite estricto antes de memcmp en ocfs2_xattr_find_entry() xattr en ocfs2 puede ser 'non-indexed', lo que se guardó con espacio adicional solicitado. Es mejor comprobar si la memoria está fuera de los límites antes de memcmp, aunque esta posibilidad proviene principalmente de imágenes venenosas creadas.
