Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel (Intel IoTG) vulnerabilities (USN-6686-5)

high Nessus Plugin ID 192638

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6686-5 advisory.

 - In the Linux kernel before 5.17, an error path in dwc3_qcom_acpi_register_core in drivers/usb/dwc3/dwc3-qcom.c lacks certain platform_device_put and kfree calls. (CVE-2023-22995)

 - 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)

 - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

 - 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)

 - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

 - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
