UBUNTU-CVE-2025-38117: Use After Free

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

The supplied CVSS vector indicates local access, low attack complexity, low privileges, and no user interaction are required. The issue can result in a use-after-free condition with high impact to confidentiality, integrity, and availability.

Q: Which Ubuntu kernel packages are identified as affected?

The listed software includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, and their FIPS variants: ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

Q: What failure mode may indicate exposure?

The vulnerability involves concurrent access to the Bluetooth mgmt_pending list and may cause a slab use-after-free. The provided crash example reports a KASAN slab-use-after-free in hci_sock_get_channel, reached through mgmt_pending_find during Bluetooth management activity.
