NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-block-ssh package and not the qemu-block-ssh package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.
