CVE-2023-52662

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/vmwgfx: soluciona un memleak en vmw_gmrid_man_get_node Cuando falla ida_alloc_max, se deben liberar los recursos asignados anteriormente, incluido *res asignado por kmalloc y ttm_resource_init.

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: fix a memleak in vmw_gmrid_man_get_node When ida_alloc_max fails, resources allocated before should be freed, including *res allocated by kmalloc and ttm_resource_init.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.
