Details
Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde
discovered that an untrusted hypervisor could inject malicious #VC
interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw
is known as WeSee. A local attacker in control of the hypervisor could use
this to expose sensitive information or possibly execute arbitrary code in
the trusted execution environment. (CVE-2024-25742)
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:
- TTY drivers;
- SMB network file system;
- Netfilter;
- Bluetooth subsystem
