CVE-2019-5489: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.8% chance of exploitation in the next 30 days.

The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.

Affected products

• Linux Linux Kernel: up to and including 4.19.13
• Netapp Active Iq Performance Analytics Services: affected versions not specified
• Netapp Element Software Management Node: affected versions not specified
