GHSA-53G5-98C7-5CWC
Vulnerability from github – Published: 2026-10-23 12:31 – Updated: 2026-10-23 12:31In the Linux kernel, the following vulnerability has been resolved:
host1x: bus: Fix missing ops null check in error teardown
In host1x_device_init(), the error teardown paths do not check client->ops before dereferencing it, unlike the forward init paths which correctly guard with 'client->ops &&'. This can result in a NULL pointer dereference if client->ops is NULL.
Fix by adding the missing client->ops check in both the teardown and teardown_late labels.
