TensorFlow is an open source platform for machine learning. In affected versions the async implementation of `CollectiveReduceV2` suffers from a memory leak and a use after free. This occurs due to the asynchronous computation and the fact that objects that have been `std::move()`d from are still accessed. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, as this version is the only one that is also affected.
CWE-416
CVE-2021-4102
Use after free in V8 in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
CVE-2021-41043
Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact.
CVE-2021-4099
Use after free in Swiftshader in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
CVE-2021-4083
A read-after-free memory flaw was found in the Linux kernel’s garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4.
CVE-2021-40725
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by a use-after-free vulnerability when processing AcroForm listbox that could result in arbitrary code execution in the context of the current user. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
