Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: validate payload size in ipc response

If installing malicious ksmbd-tools, ksmbd.mountd can return invalid ipc
response to ksmbd kernel server. ksmbd should validate payload size of
ipc response from ksmbd.mountd to avoid memory overrun or
slab-out-of-bounds. This patch validate 3 ipc response that has payload.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ksmbd: validar el tamaño del payload en la respuesta de ipc Si instala herramientas ksmbd maliciosas, ksmbd.mountd puede devolver una respuesta de ipc no válida al servidor del kernel de ksmbd. ksmbd debe validar el tamaño del payload de la respuesta ipc de ksmbd.mountd para evitar el desbordamiento de la memoria o los límites. Este parche valida 3 respuestas ipc que tienen payload.
