CVE-2024-38585

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tools/nolibc/stdlib: corrige el error de memoria en realloc() Pase user_p_len a memcpy() en lugar de heap->len para evitar que realloc() copie un tamaño extra de(heap) bytes más allá de la región asignada.

In the Linux kernel, the following vulnerability has been resolved: tools/nolibc/stdlib: fix memory error in realloc() Pass user_p_len to memcpy() instead of heap->len to prevent realloc() from copying an extra sizeof(heap) bytes from beyond the allocated region.

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.
