Summary
qemu security update
Details

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process.(CVE-2026-48914)
