+
+===[[Internet_Browser|Web-applets]]===
+The [[11.0.0|CFI]] code was updated.
+
+The add/sub instruction was replaced with eor. Hence, the additional code at func entry/exit is now identical. The code now does:
+* The low 40-bits of x30 are extracted, then multiplied with x18.
+* <code>crc32x w17, w16, x17</code> (which uses the above value - x16 was set to sp after the above bitfield-extract)
+* x17 is multiplied with x18 again.
+* <code>crc32x w17, wzr, x17</code>
+* Then lastly the eor instruction is used with x30, with x17 shifted to bit40.
+
+A vuln with RNG was [[Switch_System_Flaws|fixed]].
