CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the NVMe-oF/TCP subsystem in the Linux kernel. A remote attacker can send specially crafted data to the system, trigger an out-of-bounds read error and read contents of memory.

5) Out-of-bounds read (CVE-ID: CVE-2023-6560)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in io_uring SQ/CQ rings functionality in the Linux kernel. A local user can trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

6) Resource management error (CVE-ID: CVE-2024-0607)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the nft_byteorder_eval() function in the Netfilter subsystem. A local user can perform a denial of service (DoS) attack.

7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-25744)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to missing access restrictions related to arch/x86/coco/tdx/tdx.c and arch/x86/mm/mem_encrypt_amd.c. An untrusted VMM can trigger int80 syscall handling at any given point and perform a denial of service (DoS) attack.
