Descriptions

In the Linux kernel, the following vulnerability has been resolved: firewire: nosy: ensure user_length is taken into account when fetching packet contents Ensure that packet_buffer_get respects the user_length provided. If
the length of the head packet exceeds the user_length, packet_buffer_get
will now return 0 to signify to the user that no data were read
and a larger buffer size is required. Helps prevent user space overflows.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firewire: nosy: asegúrese de que se tenga en cuenta la longitud de usuario al recuperar el contenido del paquete. Asegúrese de que paquete_buffer_get respete la longitud de usuario proporcionada. Si la longitud del paquete principal excede la longitud del usuario, paquete_buffer_get ahora devolverá 0 para indicarle al usuario que no se leyeron datos y que se requiere un tamaño de búfer mayor. Ayuda a evitar el desbordamiento del espacio del usuario.

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
