CVE-2019-5489
- Severity: medium (CVSS 5.5 v3.0)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.8% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2019-01-07 · updated 2026-06-17
- Weakness: CWE-319
Description
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 kernel: through 4.19.13
- NetApp Active Iq Performance Analytics Services: all versions
- NetApp Element Software Management Node: all versions
