UBUNTU-CVE-2024-23851: Medium severity ubuntu/linux-aws vulnerability

Q: What level of access does an attacker need to exploit this issue?

The vulnerability has local attack vector and low privileges required. An attacker would need local access and an account or process with the required low-level privileges to invoke the affected device-mapper ioctl path.

Q: What is the likely impact if exploitation succeeds?

Successful exploitation can cause a denial of service by triggering an oversized allocation attempt and crashing the kernel. The provided severity vector indicates no confidentiality or integrity impact.

Q: Which Ubuntu kernel packages are identified as affected?

The affected software list includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

Q: How can I determine whether a system may be affected?

Check whether the system uses one of the listed Ubuntu kernel packages and whether its kernel is through version 6.7.1. The issue is in the device-mapper ioctl handling path in drivers/md/dm-ioctl.c.

Published Jan 23, 2024

Updated

copyparams in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than INTMAX bytes, and crash, because of a missing paramkernel->datasize check. This is related to ctlioctl.

Frequently Asked Questions

What level of access does an attacker need to exploit this issue?

The vulnerability has local attack vector and low privileges required. An attacker would need local access and an account or process with the required low-level privileges to invoke the affected device-mapper ioctl path.

What is the likely impact if exploitation succeeds?

Successful exploitation can cause a denial of service by triggering an oversized allocation attempt and crashing the kernel. The provided severity vector indicates no confidentiality or integrity impact.

Which Ubuntu kernel packages are identified as affected?

The affected software list includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

How can I determine whether a system may be affected?

Check whether the system uses one of the listed Ubuntu kernel packages and whether its kernel is through version 6.7.1. The issue is in the device-mapper ioctl handling path in drivers/md/dm-ioctl.c.
