Descriptions
In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group The perf tool allows users to create event groups through following
cmd [1], but the driver does not check whether the array index is out
of bounds when writing data to the event_group array. If the number of
events in an event_group is greater than HNS3_PMU_MAX_HW_EVENTS, the
memory write overflow of event_group array occurs. Add array index check to fix the possible array out of bounds violation,
and return directly when write new events are written to array bounds. There are 9 different events in an event_group.
[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/perf: hisi: hns3: corrige el acceso fuera de los límites cuando el grupo de eventos es válido. La herramienta perf permite a los usuarios crear grupos de eventos mediante el siguiente cmd [1], pero el controlador no comprueba si el índice de la matriz está fuera de los límites al escribir datos en la matriz event_group. Si el número de eventos en un event_group es mayor que HNS3_PMU_MAX_HW_EVENTS, se produce un desbordamiento de escritura en la memoria de la matriz event_group. Agregue la verificación del índice de la matriz para corregir la posible infracción de la matriz fuera de los límites y regrese directamente cuando se escriban nuevos eventos en los límites de la matriz. Hay 9 eventos diferentes en un grupo de eventos. [1] estadística de rendimiento -e '{pmu/event1/, ...,pmu/event9/}

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.
