Description
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.
Ubuntu-Description
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).
Notes
| tyhicks | Setting the priority to low since the ARC EMAC ethernet device driver
is for legacy FPGA boards which are unlikely to have a high numbers of users |
