UBUNTU-CVE-2025-38174: High severity ubuntu/linux-aws vulnerability

Q: Is this remotely exploitable?

No. The supplied CVSS vector marks attack vector as local and requires low privileges, with no user interaction required.

Q: What is the expected security impact?

The impact is availability only: the issue can crash affected systems. The supplied CVSS vector indicates no confidentiality or integrity impact.

Q: What condition leads to the crash?

The failure is associated with a configuration request being scheduled twice, allowing two worker executions to dequeue the same request and perform a double list deletion.

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

The listed packages are 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.

Updated

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Do not double dequeue a configuration request Some of our devices crash in tbcfgrequestdequeue(): general protection fault, probably for non-canonical address 0xdead000000000122 CPU: 6 PID: 91007 Comm: kworker/6:2 Tainted: G U W 6.6.65 RIP: 0010:tbcfgrequestdequeue+0x2d/0xa0 Call Trace: <TASK> ? tbcfgrequestdequeue+0x2d/0xa0 tbcfgrequestwork+0x33/0x80 workerthread+0x386/0x8f0 kthread+0xed/0x110 retfromfork+0x38/0x50 retfromforkasm+0x1b/0x30 The circumstances are unclear, however, the theory is that tbcfgrequestwork() can be scheduled twice for a request: first time via frame.callback from ringwork() and second time from tbcfgrequest(). Both times kworkers will execute tbcfgrequestdequeue(), which results in double listdel() from the ctl->requestqueue (the list poison deference hints at it: 0xdead000000000122). Do not dequeue requests that don't have TBCFGREQUESTACTIVE bit set.
