5.5 · MEDIUM
Published May 1, 2025 linux CWE-476 EPSS 0.18% (7th pctl)

Overview

CVE-2025-37759 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 1, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

ublk: fix handling recovery & reissue in ublk_abort_queue()

Commit 8284066946e6 ("ublk: grab request reference when the request is handled

by userspace") doesn't grab request reference in case of recovery reissue.

Then the request can be requeued & re-dispatch & failed when canceling

uring command.

If it is one zc request, the request can be freed before io_uring

returns the zc buffer back, then cause kernel panic:
