CVE-2024-38587

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Speakup: corrige el error sizeof() vs ARRAY_SIZE() El puntero "buf" es una matriz de valores u16. Este código debería usar ARRAY_SIZE() (que es 256) en lugar de sizeof() (que es 512), de lo contrario aún puede salirse de los límites.

In the Linux kernel, the following vulnerability has been resolved: speakup: Fix sizeof() vs ARRAY_SIZE() bug The "buf" pointer is an array of u16 values. This code should be using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512), otherwise it can the still got out of bounds.

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.
