CVE-2024-36914

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: omitir la reescritura cuando no sea aplicable [POR QUÉ] el detector de errores de seguridad de memoria dinámica (KASAN) detecta y genera mensajes de error "ERROR: KASAN: slab-out- of-bounds" como conector de reescritura no admite ciertas funciones que no están inicializadas. [CÓMO] Omítelos cuando el tipo de conector sea DRM_MODE_CONNECTOR_WRITEBACK.

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Skip on writeback when it's not applicable [WHY] dynamic memory safety error detector (KASAN) catches and generates error messages "BUG: KASAN: slab-out-of-bounds" as writeback connector does not support certain features which are not initialized. [HOW] Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.

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.
