CVE-2026-23328

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> accel/amdxdna: Fix NULL pointer dereference of mgmt_chann<br /> <br /> mgmt_chann may be set to NULL if the firmware returns an unexpected<br /> error in aie2_send_mgmt_msg_wait(). This can later lead to a NULL<br /> pointer dereference in aie2_hw_stop().<br /> <br /> Fix this by introducing a dedicated helper to destroy mgmt_chann<br /> and by adding proper NULL checks before accessing it.
