 https://ubuntu.com/security/notices/USN-4208-1
Description:
 A memory leak in the fastrpc_dma_buf_attach() function in
 drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to
 cause a denial of service (memory consumption) by triggering
 dma_get_sgtable() failures, aka CID-fc739a058d99.
Ubuntu-Description:
 It was discovered in the Qualcomm FastRPC Driver for the Linux kernel did
 not properly deallocate memory in certain error conditions. A local
 attacker could use this to cause a denial of service (memory exhaustion).
