CVE-2024-27403

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nft_flow_offload: restablece dst en el objeto de ruta después de configurar el flujo dst se transfiere al objeto de flujo, el objeto de ruta ya no es propietario. Restablezca el dst en el objeto de ruta; de lo contrario, si flow_offload_add() fallo, la ruta de error libera el dst dos veces, lo que provoca un desbordamiento insuficiente del recuento.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_flow_offload: reset dst in route object after setting up flow dst is transferred to the flow object, route object does not own it anymore. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow.

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. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
