UBUNTU-CVE-2024-38612: Use After Free

Q: Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.

Q: What configuration and failure conditions reach the flawed error path?

The issue occurs when CONFIG_IPV6_SEG6_LWTUNNEL is not defined and seg6_hmac_init() fails during seg6_init(). In that path, genl_unregister_family() is not called.

Q: What code history is relevant when assessing a source-based backport?

The issue has existed since commit 46738b1317e1, which added the option controlling lwtunnel support. Commit 5559cea2d5aa changed the relevant error path to use genl_unregister_family(), and the referenced fix is commit 160e9d2752181fcf18c662e74022d77d3164cd45.

Published Jun 19, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6init() is wrong in case CONFIGIPV6SEG6LWTUNNEL is not defined. In that case if seg6hmacinit() fails, the genlunregisterfamily() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregisterpernetsubsys() with genlunregisterfamily() in this error path.

Frequently Asked Questions

Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.

What configuration and failure conditions reach the flawed error path?

The issue occurs when CONFIG_IPV6_SEG6_LWTUNNEL is not defined and seg6_hmac_init() fails during seg6_init(). In that path, genl_unregister_family() is not called.

What code history is relevant when assessing a source-based backport?

The issue has existed since commit 46738b1317e1, which added the option controlling lwtunnel support. Commit 5559cea2d5aa changed the relevant error path to use genl_unregister_family(), and the referenced fix is commit 160e9d2752181fcf18c662e74022d77d3164cd45.
