Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm: vc4: Fix possible null pointer dereference In vc4_hdmi_audio_init() of_get_address() may return
NULL which is later dereferenced. Fix this bug by adding NULL check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: vc4: corrige posible desreferencia del puntero nulo En vc4_hdmi_audio_init() of_get_address() puede devolver NULL, que luego se desreferencia. Corrija este error agregando una verificación NULL. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.

Fix this bug by adding NULL check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
