+Subject: [PATCH] Add more value barriers to avoid compiler induced side
+ channels
+
+The paper https://arxiv.org/pdf/2410.13489 claims that on specific
+architectures Clang and GCC may introduce jumps here. The donna128
+issues only affect 32-bit processors, which explains why we would not
+see it in the x86-64 valgrind runs.
+
+The GHASH leak would seem to be generic but the authors only observed
+it on RISC-V.
+
+CVE: CVE-2024-50382
+CVE: CVE-2024-50383
+Upstream-Status: Backport [https://github.com/randombit/botan/commit/53b0cfde580e86b03d0d27a488b6c134f662e957]
