CVE-2019-18786

Published: 6 November 2019

In the Linux kernel through 5.3.8, f->fmt.sdr.reserved is uninitialized in rcar_drif_g_fmt_sdr_cap in drivers/media/platform/rcar_drif.c, which could cause a memory disclosure problem.

From the Ubuntu Security Team

It was discovered that the Renesas Digital Radio Interface (DRIF) driver in the Linux kernel did not properly initialize data. A local attacker could possibly use this to expose sensitive information (kernel memory).

Priority

Low

CVSS 3 base score: 5.5
