From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Shruti Bihani Date: Thu, 6 Jul 2023 08:41:56 +0000 Subject: [PATCH] Fix Segv on unknown address error flagged by fuzzer test. The error is thrown when the destructor tries to free pointer memory. This is happening for cases where the pointer was not initialized. Initializing it to a default value fixes the error. Bug: 245135112 Test: Build mtp_host_property_fuzzer and run on the target device (cherry picked from commit 3afa6e80e8568fe63f893fa354bc79ef91d3dcc0) (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:99d0823ca2b8275f000a437150fb8d1938b1b31a) Merged-In: I255cd68b7641e96ac47ab81479b9b46b78c15580 Change-Id: I255cd68b7641e96ac47ab81479b9b46b78c15580 --- media/mtp/MtpProperty.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/media/mtp/MtpProperty.h b/media/mtp/MtpProperty.h index 03c08e1eed..45fcbe8917 100644 --- a/media/mtp/MtpProperty.h +++ b/media/mtp/MtpProperty.h @@ -24,6 +24,9 @@ namespace android { class MtpDataPacket; struct MtpPropertyValue { + // pointer str initialized to NULL so that free operation + // is not called for pre-assigned value + MtpPropertyValue() : str (NULL) {} union { int8_t i8; uint8_t u8;
