Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is
assigned to mhdp_state->current_mode, and there is a dereference of it in
drm_mode_set_name(), which will lead to a NULL pointer dereference on
failure of drm_mode_duplicate(). Fix this bug add a check of mhdp_state->current_mode.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: bridge: cdns-mhdp8546: corrige posible desreferencia del puntero nulo En cdns_mhdp_atomic_enable(), el valor de retorno de drm_mode_duplicate() se asigna a mhdp_state->current_mode, y hay una desreferencia de él en drm_mode_set_name(), lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate(). Solucione este error y agregue una verificación de mhdp_state->current_mode.

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.
