There seems to be an early return in Java_sun_nio_ch_sctp_SctpChannelImpl_receive0 that misses freeing memory.
Sonar reports : https://sonarcloud.io/project/issues?id=shipilev_jdk&languages=c&open=AXck8Cl0BBG2CXpcnjFu&resolved=false&severities=BLOCKER&types=BUG Potential leak of memory pointed to by 'newBuf' I adjusted the early return and added freeing memory . Btw. while adjusting Java_sun_nio_ch_sctp_SctpChannelImpl_receive0 , I started to wonder what happens to the allocated memory in the same file in handleSendFailed ( if ((addressP = malloc(dataLength)) == NULL) ) in early return cases incl. the CHECK_NULL , is there some deallocation missing there too ? ------------- Commit messages: - JDK-8261601 Changes: https://git.openjdk.java.net/jdk/pull/2540/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=2540&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8261601 Stats: 2 lines in 1 file changed: 1 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/2540.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/2540/head:pull/2540 PR: https://git.openjdk.java.net/jdk/pull/2540
