Unity Linux 20.1050e Security Update: kernel (UTSA-2025-990116)

medium Nessus Plugin ID 272481

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990116 advisory.

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

 extcon: Modify extcon device to be created after driver data is set

 Currently, someone can invoke the sysfs such as state_show() intermittently before dev_set_drvdata() is done.
 And it can be a cause of kernel Oops because of edev is Null at that time.
 So modified the driver registration to after setting drviver data.

 - Oops's backtrace.

 Backtrace:
 [<c067865c>] (state_show) from [<c05222e8>] (dev_attr_show) [<c05222c0>] (dev_attr_show) from [<c02c66e0>] (sysfs_kf_seq_show) [<c02c6648>] (sysfs_kf_seq_show) from [<c02c496c>] (kernfs_seq_show) [<c02c4938>] (kernfs_seq_show) from [<c025e2a0>] (seq_read) [<c025e11c>] (seq_read) from [<c02c50a0>] (kernfs_fop_read) [<c02c5064>] (kernfs_fop_read) from [<c0231cac>] (__vfs_read) [<c0231c5c>] (__vfs_read) from [<c0231ee0>] (vfs_read) [<c0231e34>] (vfs_read) from [<c0232464>] (ksys_read) [<c02323f0>] (ksys_read) from [<c02324fc>] (sys_read) [<c02324e4>] (sys_read) from [<c00091d0>] (__sys_trace_return)

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.

Solution

Update the affected kernel package.
