+ <p>On 32-bit computers, <c>binary_to_term/1,2</c> is now
+ more resilient against corrupted binaries containing maps
+ in the external format.</p>
+ <p>
+ Own Id: OTP-17604</p>
+ </item>
+ <item>
+ <p>
+ A call to <c>process_info(Pid, status)</c> could
+ erroneously report the status <c>running</c> when it
+ should have reported <c>waiting</c>. This occurred when
+ the calling process was executing on a higher priority
+ than the process being inspected. This bug has been
+ present since OTP 21.0 (erts version 10.0).</p>
+ <p>
+ Own Id: OTP-17628</p>
+ </item>
+ <item>
+ <p>
+ A race between an exiting port and handling of
+ simultaneously received signals to that port could cause
+ a runtime system crash. The effected signals are
+ <c>link</c>, <c>monitor</c> and <c>demonitor</c>. On OTP
+ 22 a similiar race could also cause a memory leak when
+ receiving an <c>unlink</c> signal.</p>
+ <p>
+ Own Id: OTP-17642 Aux Id: PR-5248 </p>
+ </item>
+ <item>
+ <p>
+ The message queue of a process entered an inconsistent
+ state after a <c>receive</c> expression with an invalid
+ timeout value was executed. If the exception raised due
+ to the invalid timeout value was caught, the following
+ <c>receive</c> expression executed by the process could
+ fail to match messages already present in the message
+ queue.</p>
+ <p>
+ On OTP 24 this could also cause the whole runtime system
+ to crash.</p>
+ <p>
+ Own Id: OTP-17651 Aux Id: GH-5235, PR-5244 </p>
+ </item>
+ <item>
+ <p>
+ Sending a <c>Port ! {PortOwner, close}</c> signal from a
+ process other than the port owner could erroneously
+ trigger a <c>badsig</c> exit signal being sent to the
+ port owner process even though the correct
+ <c>PortOwner</c> had been passed in the signal.</p>
+ <p>
+ Own Id: OTP-17665 Aux Id: PR-5248 </p>
+ </item>
+ <item>
+ <p>
+ This fixes a bug in <c>erts_factory_undo</c> that caused
+ the heap to not be reset correctly. The
+ <c>erts_factory_undo</c> function is, for example, called
+ when a <c>binary_to_term/1</c> call fails to reset the
+ heap to its state before the <c>binary_to_term/1</c>
+ call. This can cause the heap to contain invalid terms
+ which potentially can cause issues (e.g., crashes) when
+ the whole heap is scanned.</p>
+ <p>
+ Own Id: OTP-17677</p>
+ </item>
+ <item>
+ <p>Fix bug in <c>persistent_term</c> when a key-value
+ pair contains a magic reference that is referred more
+ than once. Magic references are NIF resources or returned
+ from BIFs like <c>ets:new</c>, <c>atomics:new</c>. The
+ bug could cause the memory of the referred resource to be
+ prematurely deallocated.</p> <p>The bug also apply to
+ magic references in message passing on a runtime built
+ with configure option
+ <c>--enable-sharing-preserving</c>.</p> <p>Bug exist for
+ 64-bit since OTP-24.0 and for 32-bit since OTP-20.0.</p>
