CVE-2025-38587

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipv6: corrección de un posible bucle infinito en fib6_info_uses_dev(). fib6_info_uses_dev() parece depender de RCU sin protección explícita. Al igual que la corrección anterior en rt6_nlmsg_size(), debemos asegurarnos de que fib6_del_route() o fib6_add_rt2node() no hayan eliminado el ancla de la lista; de lo contrario, corremos el riesgo de un bucle infinito.

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible infinite loop in fib6_info_uses_dev() fib6_info_uses_dev() seems to rely on RCU without an explicit protection. Like the prior fix in rt6_nlmsg_size(), we need to make sure fib6_del_route() or fib6_add_rt2node() have not removed the anchor from the list, or we risk an infinite loop.

It was discovered that improper initialization of CPU cache memory could allow a local attacker with hypervisor access to overwrite SEV-SNP guest memory resulting in loss of data integrity. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
