NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-block-curl package and not the qemu-kvm-block-curl package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
