Description

A flaw was found in the Linux kernel's AF_XDP (eXpress Data Path) subsystem. The AF_XDP bind operation fails to validate the Maximum Transmission Unit (MTU) against the usable frame space provided by the UMEM (User Memory) chunk. This can lead to situations where the configured MTU does not fit, potentially causing network communication failures or system instability. A local attacker could potentially leverage this vulnerability to disrupt network services, resulting in a denial of service.
