Ubuntu Security Notice USN-6608-2

Ubuntu Security Notice 6608-2 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information. Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle inactive elements in its PIPAPO data structure, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice USN-6628-1

Ubuntu Security Notice 6628-1 - Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service.

Ubuntu Security Notice USN-6609-1

Ubuntu Security Notice 6609-1 - Lin Ma discovered that the netfilter subsystem in the Linux kernel did not properly validate network family support while creating a new netfilter table. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice USN-6606-1

Ubuntu Security Notice 6606-1 - It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice USN-6603-1

Ubuntu Security Notice 6603-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information. Budimir Markovic, Lucas De Marchi, and Pengfei Xu discovered that the perf subsystem in the Linux kernel did not properly validate all event sizes when attaching new events, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

CVE-2023-32463: DSA-2023-200: Security Update for Dell VxRail for Multiple Third-Party Component Vulnerabilities

Dell VxRail, version(s) 8.0.100 and earlier contain a denial-of-service vulnerability in the upgrade functionality. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to degraded performance and system malfunction.

CVE-2023-28043: DSA-2023-164: Dell Secure Connect Gateway Security Update for Multiple Vulnerabilities

Dell SCG 5.14 contains an information disclosure vulnerability during the SRS to SCG upgrade path. A remote low privileged malicious user could potentially exploit this vulnerability to retrieve the plain text.

CVE-2022-38096: Invalid Bug ID

A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
