Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-422683)

medium Nessus Plugin ID 267890

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-2025-422683 advisory.

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

 RDMA/uverbs: Prevent integer overflow issue

 In the expression cmd.wqe_size * cmd.wr_count, both variables are u32 values that come from the user so the multiplication can lead to integer wrapping. Then we pass the result to uverbs_request_next_ptr() which also could potentially wrap. The cmd.sge_count * sizeof(struct ib_uverbs_sge) multiplication can also overflow on 32bit systems although it's fine on 64bit systems.

 This patch does two things. First, I've re-arranged the condition in uverbs_request_next_ptr() so that the use controlled variable len is on one side of the comparison by itself without any math. Then I've modified all the callers to use size_mul() for the multiplications.

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.
