Vulnerability from github – Published: 2026-03-25 12:30 – Updated: 2026-04-23 21:31

Details

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

accel/amdxdna: Fix NULL pointer dereference of mgmt_chann

mgmt_chann may be set to NULL if the firmware returns an unexpected error in aie2_send_mgmt_msg_wait(). This can later lead to a NULL pointer dereference in aie2_hw_stop().

Fix this by introducing a dedicated helper to destroy mgmt_chann and by adding proper NULL checks before accessing it.

Severity

5.5 (Medium)
