NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Debian.
See How to fix? for Debian:13 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.
