CVE-2026-72056 in Linuxinformación

Resumen

por MITRE • 2026-08-15

In the Linux kernel, the following vulnerability has been resolved:

net: ena: clean up XDP TX queues when regular TX setup fails

create_queues_with_size_backoff() creates XDP TX queues before setting up the regular TX path. If the subsequent allocation or creation of regular TX queues fails, the error handling paths omit the teardown of the XDP TX queues, leading to a resource leak.

Fix this by explicitly destroying the XDP TX queue subset at the two missing failure points.

The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc7.

An x86_64 allyesconfig build showed no new warnings. As we do not have an ENA device to test with, no runtime testing was able to be performed.
