CVE-2022-3640 linux-kvm vulnerabilities
linux-kvm vulnerabilities
It was discovered that a use-after-free vulnerability existed in the
Bluetooth stack in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3640)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- SCSI subsystem;
- Network file system (NFS) client;
- NILFS2 file system;
- File systems infrastructure;
- Memory management;
- Bluetooth subsystem;
- Network traffic control;
- USB sound devices;
