Description

In the Linux kernel, the following vulnerability has been resolved: nvmet: avoid potential UAF in nvmet_req_complete() An nvme target ->queue_response() operation implementation may free the request passed as argument. Such implementation potentially could result in a use after free of the request pointer when percpu_ref_put() is called in nvmet_req_complete(). Avoid such problem by using a local variable to save the sq pointer before calling __nvmet_req_complete(), thus avoiding dereferencing the req pointer after that function call.

Affected configurations

• linux linux kernel (>= 4.8 < 4.14.311) • linux linux kernel (>= 4.15 < 4.19.279) • linux linux kernel (>= 4.20 < 5.4.238) • linux linux kernel (>= 5.5 < 5.10.176) • linux linux kernel (>= 5.11 < 5.15.104) • linux linux kernel (>= 5.16 < 6.1.21) • linux linux kernel (>= 6.2 < 6.2.8) • linux linux kernel 6.3
