From ac5ae0a5ce22640f73677d40730a37f43df442d1 Mon Sep 17 00:00:00 2001 From: Ally Heev Date: Tue, 11 Nov 2025 13:26:42 +0530 Subject: [PATCH] tee: qcomtee: fix uninitialized pointers with free attribute Uninitialized pointers with `__free` attribute can cause undefined behavior as the memory assigned randomly to the pointer is freed automatically when the pointer goes out of scope. qcomtee doesn't have any bugs related to this as of now, but it is better to initialize and assign pointers with `__free` attribute in one statement to ensure proper scope-based cleanup Reported-by: Dan Carpenter Closes: https://lore.kernel.org/all/aPiG_F5EBQUjZqsl@stanley.mountain/ Signed-off-by: Ally Heev Reviewed-by: Sumit Garg Signed-off-by: Jens Wiklander --- drivers/tee/qcomtee/call.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/tee/qcomtee/call.c b/drivers/tee/qcomtee/call.c index cc17a48d0ab74..92e869f7467d8 100644 --- a/drivers/tee/qcomtee/call.c +++ b/drivers/tee/qcomtee/call.c @@ -645,7 +645,7 @@ static void qcomtee_get_version(struct tee_device *teedev, static void qcomtee_get_qtee_feature_list(struct tee_context *ctx, u32 id, u32 *version) { - struct qcomtee_object_invoke_ctx *oic __free(kfree); + struct qcomtee_object_invoke_ctx *oic __free(kfree) = NULL; struct qcomtee_object *client_env, *service; struct qcomtee_arg u[3] = { 0 }; int result; -- 2.47.3
