CVE-2016-10906
Published: 19 August 2019
An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use-after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.
From the Ubuntu Security Team
It was discovered that a race condition existed in the ARC EMAC ethernet driver for the Linux kernel, resulting in a use-after-free vulnerability. An attacker could use this to cause a denial of service (system crash).
