From 855ae72c20310e5402b2317fc537d911e87537ef Mon Sep 17 00:00:00 2001 From: Jesse Zhang Date: Wed, 24 Apr 2024 17:10:46 +0800 Subject: [PATCH] drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 88a9a467c548d0b3c7761b4fd54a68e70f9c0944 ] Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001. V2: To really improve the handling we would actually need to have a separate value of 0xffffffff.(Christian) Signed-off-by: Jesse Zhang Suggested-by: Christian König Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin --- drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c index 1904edf68407..88a3aa36b41d 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c @@ -742,7 +742,8 @@ int amdgpu_vce_ring_parse_cs(struct amdgpu_cs_parser *p, uint32_t created = 0; uint32_t allocated = 0; uint32_t tmp, handle = 0; - uint32_t *size = &tmp; + uint32_t dummy = 0xffffffff; + uint32_t *size = &dummy; unsigned int idx; int i, r = 0;
