high Tenable Self-Hosted Container Security Plugin ID 462553

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to
 write data beyond its allocated memory. This occurs when cpu_physical_memory_map() returns a shorter
 length than expected, leading to an out-of-bounds write. Successful exploitation could result in
 unauthorized access to guest memory or corruption of heap-allocated objects, potentially causing
 information disclosure, data integrity issues, or a denial of service. (CVE-2026-3842)

Update the qemu library and its related packages to version 1:10.0.8+ds-0+deb13u1+e2 or later.
