Unity Linux 20.1050e Security Update: kernel (UTSA-2026-100135)
high Nessus Plugin ID 336955
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-2026-100135 advisory.In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Add alignment check for event ring read pointer
Though we do check the event ring read pointer by is_valid_ring_ptr to make sure it is in the buffer range, but there is another risk the pointer may be not aligned. Since we are expecting event ring elements are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer could lead to multiple issues like DoS or ring buffer memory corruption.
So add a alignment check for event ring read pointer.
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.See Also
