| Revision Date: | 2018-03-08 | Version: | 1 | | Title: | CVE-2018-7757 on Ubuntu 18.04 LTS (bionic) - medium. | | Description: | Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file. It was discovered that a memory leak existed in the SAS driver subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion).
