Hi,
The following vulnerability was published for qemu.
CVE-2023-1386[0]:
| A flaw was found in the 9p passthrough filesystem (9pfs)
| implementation in QEMU. When a local user in the guest writes an
| executable file with SUID or SGID, none of these privileged bits are
| correctly dropped. As a result, in rare circumstances, this flaw
| could be used by malicious users in the guest to elevate their
| privileges within the guest and help a host local user to elevate
| privileges on the host.
