CVE-2024-35947

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dyndbg: corrige el antiguo BUG_ON en >control parser. Corrige un BUG_ON de 2009. Incluso si parece "unreachable" (realmente no lo miré), asegurémonos eliminándolo. haciendo pr_err y devuelve -EINVAL en su lugar.

In the Linux kernel, the following vulnerability has been resolved: dyndbg: fix old BUG_ON in >control parser Fix a BUG_ON from 2009. Even if it looks "unreachable" (I didn't really look), lets make sure by removing it, doing pr_err and return -EINVAL instead.

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.
