GHSA-fvf2-2vh9-p4j4 PUBLISHED CVSS 5.5 MEDIUM

Record from GitHub Advisory Database · Published September 17, 2025

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: u_serial: Add null pointer check in gserial_suspend Consider a case where gserial_disconnect has already cleared gser->ioport. And if gserial_suspend gets called afterwards, it will lead to accessing of gser->ioport and thus causing null pointer dereference. Avoid this by adding a null pointer check. Added a static spinlock to prevent gser->ioport from becoming null after the newly added null pointer check.
