An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-146669 advisory.

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

    usb: gadget: f_fs: Fix Use-After-Free in AIO error path

    In ffs_epfile_write_iter() and ffs_epfile_read_iter(), when ffs_epfile_io()     fails with an error other than -EIOCBQUEUED, the io_data structure (`p`) is     freed. However, for AIO operations, the kiocb cancel function was already     armed and kiocb->private was set to `p`.

    If a concurrent cancel operation (such as sys_io_cancel()) executes after     ffs_epfile_io() fails but before the function frees `p`, a Use-After-Free     can occur when the cancellation handler accesses the freed pointer.

    To securely fix this race condition, we must properly un-arm the     cancellation. Invoking `kiocb->ki_complete()` does exactly this by     acquiring `ctx->ctx_lock` and safely removing the kiocb from the active     sequence. In doing so, it ensures that a parallel io_cancel can no longer     discover the kiocb, effectively closing the race window.

    We then return -EIOCBQUEUED to notify the VFS layer that the kiocb has been     consumed and it should avoid attempting to complete the request again or     triggering subsequent completion handlers.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-9002-1 advisory.

    It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task     work when processing certain wait operations, leading to the operation being performed in the wrong task     context. A local attacker could possibly use this to cause a denial of service (system crash).
