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.

 - ARM64 architecture,
 - Block layer subsystem,
 - Bluetooth drivers,
 - Clock framework and drivers,
 - FireWire subsystem,
 - GPU drivers,
 - InfiniBand drivers,
 - Multiple devices driver,
 - EEPROM drivers,
 - Network drivers,
 - Pin controllers subsystem,
 - Remote Processor subsystem,
 - S/390 drivers,
 - SCSI drivers,
 - TTY drivers,
 - 9P distributed file system,
 - Network file system client,
 - SMB network file system,
 - Socket messages infrastructure,
 - Dynamic debug library,
 - Bluetooth subsystem,
 - Networking core,
 - IPv4 networking,
 - IPv6 networking,
 - Multipath TCP,
 - Netfilter,
 - NSH protocol,
 - Phonet protocol,
