USN-6921-1: Linux kernel vulnerabilities

Read Time:36 Second

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-2024-35990, CVE-2024-35997, CVE-2024-35992, CVE-2024-35984,
CVE-2024-36008, CVE-2024-36016)

USN-6922-1: Linux kernel vulnerabilities

Read Time:26 Second

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel when modifying certain settings values through debugfs.
A privileged local attacker could use this to cause a denial of service.
(CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device
volume management subsystem did not properly validate logical eraseblock
sizes in certain situations. An attacker could possibly use this to cause a
denial of service (system crash). (CVE-2024-25739)
