VAR-201812-0558

Vulnerability from variot - Updated: 2025-01-30 20:59

The Bluetooth subsystem in QEMU mishandles negative values for length variables, leading to memory corruption. QEMU Contains an integer overflow vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. QEMU is prone to an integer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Attackers can exploit this issue to crash the QEMU instance, resulting in a denial-of-service condition. Due to the nature of this issue, code execution may be possible but this has not been confirmed
