CVE-2024-38591

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/hns: corrige el punto muerto en eventos asíncronos de SRQ. Es posible que se requiera xa_lock para la tabla SRQ en AEQ. Utilice xa_store_irq()/ xa_erase_irq() para evitar un punto muerto.

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix deadlock on SRQ async events. xa_lock for SRQ table may be required in AEQ. Use xa_store_irq()/ xa_erase_irq() to avoid deadlock.

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.
