CVE-2024-36959

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: pinctrl: devicetree: corrige la fuga de recuento de referencia en pinctrl_dt_to_map() Si no asignamos el búfer de nombre de propiedad, debemos eliminar el recuento de referencias que acabamos de tomar. Debido a que pinctrl_dt_free_maps() incluye la operación de eliminación, aquí la llamamos directamente.

In the Linux kernel, the following vulnerability has been resolved: pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map() If we fail to allocate propname buffer, we need to drop the reference count we just took. Because the pinctrl_dt_free_maps() includes the droping operation, here we call it directly.

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.
