A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem. Se encontró una falla de use-after-free en vmxnet3_rq_alloc_rx_buf en drivers/net/vmxnet3/vmxnet3_drv.c en el controlador NIC Ethernet vmxnet3 de VMware en el kernel de Linux. Este problema podría permitir que un atacante local bloquee el sistema debido a una doble liberación mientras se limpia vmxnet3_rq_cleanup_all, lo que también podría provocar un problema de fuga de información del kernel. • https://access.redhat.com/security/cve/CVE-2023-4387 https://bugzilla.redhat.com/show_bug.cgi?id=2219270 https://github.com/torvalds/linux/commit/9e7fef9521e73ca8afd7da9e58c14654b02dfad8 • CWE-416: Use After Free •
