Ubuntu Security Notice 6952-2 - 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. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Kortex version 1.0 suffers from an insecure direct object reference vulnerability.
Microsoft on Tuesday shipped fixes to address a total of 90 security flaws, including 10 zero-days, of which six have come under active exploitation in the wild. Of the 90 bugs, seven are rated Critical, 79 are rated Important, and one is rated Moderate in severity. This is also in addition to 36 vulnerabilities that the tech giant resolved in its Edge browser since last month. The Patch Tuesday
Ubuntu Security Notice 6954-1 - Markus Frank and Fiona Ebner discovered that QEMU did not properly handle certain memory operations, leading to a NULL pointer dereference. An authenticated user could potentially use this issue to cause a denial of service. Xiao Lei discovered that QEMU did not properly handle certain memory operations when specific features were enabled, which could lead to a stack overflow. An attacker could potentially use this issue to leak sensitive information.
Ubuntu Security Notice 6950-2 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6957-1 - 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. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6956-1 - 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. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6955-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6926-3 - 黄思聪 discovered that the NFC Controller Interface implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. 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.
