Description

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Fix GEM handle creation UAF Userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if we dereference the object after dropping the handle's reference. For that reason, dropping the handle's reference must be done *after* we are done dereferencing the object.

Affected configurations

• linux linux kernel (>= 4.4 < 4.19.270) • linux linux kernel (>= 4.20 < 5.4.229) • linux linux kernel (>= 5.5 < 5.10.164) • linux linux kernel (>= 5.11 < 5.15.89) • linux linux kernel (>= 5.16 < 6.1.7) • linux linux kernel 6.2
