Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992260)

medium Nessus Plugin ID 280283

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-2025-992260 advisory.

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

 mmc: vub300: fix return value check of mmc_add_host()

 mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path.

 So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, the timer added before mmc_add_host() needs be del.

 And this patch fixes another missing call mmc_free_host() if usb_control_msg() fails.

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.
