CVE-2024-36948

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/xe/xe_migrate: conversión a precisión de salida antes de multiplicar operandos. Abordar el posible desbordamiento como resultado de la multiplicación de dos operandos de menor precisión (u32) antes de ampliarlo a mayor precisión (u64). -v2 Corregir mensaje de commit y descripción.

In the Linux kernel, the following vulnerability has been resolved: drm/xe/xe_migrate: Cast to output precision before multiplying operands Addressing potential overflow in result of multiplication of two lower precision (u32) operands before widening it to higher precision (u64). -v2 Fix commit message and description. (Rodrigo) (cherry picked from commit 34820967ae7b45411f8f4f737c2d63b0c608e0d7)

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.
