The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6680-3 advisory.
In the Linux kernel before 6.5.9, there is a NULL pointer dereference in send_acknowledge in net/nfc/nci/spi.c. (CVE-2023-46343)
bt_sock_recvmsg in net/bluetooth/af_bluetooth.c in the Linux kernel through 6.6.8 has a use-after-free because of a bt_sock_ioctl race condition. (CVE-2023-51779)
An issue was discovered in the Linux kernel before 6.6.8. rose_ioctl in net/rose/af_rose.c has a use- after-free because of a rose_accept race condition. (CVE-2023-51782)
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
(CVE-2023-6121)
An out-of-bounds memory access flaw was found in the io_uring SQ/CQ rings functionality in the Linux kernel. This issue could allow a local user to crash the system. (CVE-2023-6560)
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the dst
array. On each iteration, 8 bytes are written, but dst
is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality. (CVE-2024-0607)
In the Linux kernel before 6.6.7, an untrusted VMM can trigger int80 syscall handling at any given point.
This is related to arch/x86/coco/tdx/tdx.c and arch/x86/mm/mem_encrypt_amd.c. (CVE-2024-25744)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
