Summary
linux-lowlatency vulnerabilities
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: - DMA engine subsystem; - HID subsystem; - I2C subsystem; - PHY drivers; - TTY drivers; - IPv4 networking; (CVE-2024-35997, CVE-2024-36016, CVE-2024-35990, CVE-2024-35984, CVE-2024-35992, CVE-2024-36008)
