File 0022-x86-efi-Fix-an-incorrect-array-size-in-kernel-alloca.patch of Package grub2
From 4bd613542a43a259c0c0f3940f0a59a6c9f133ad Mon Sep 17 00:00:00 2001 From: Peter Jones <pjones@redhat.com> Date: Tue, 11 Oct 2022 17:00:50 -0400 Subject: [PATCH 22/26] x86-efi: Fix an incorrect array size in kernel allocation In 81a6ebf62bbe166ddc968463df2e8bd481bf697c ("efi: split allocation policy for kernel vs initrd memories."), I introduced a split in the kernel allocator to allow for different dynamic policies for the kernel and the initrd allocations. Unfortunately, that change increased the size of the policy data used to make decisions, but did not change the size of the temporary storage we use to back it up and restore. This results in some of .data getting clobbered at runtime, and hilarity ensues. This patch makes the size of the backup storage be based on the size of the initial policy data.
