A memory leak in the qrtr_tun_write_iter() function in net/qrtr/tun.c in the Linux kernel before 5.3 allows attackers to cause a denial of service (memory consumption), aka CID-a21b7f0cff19.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
