Subject: [PATCH 0/4] Adding a failure check after grub_malloc()
Date: Tue, 28 Oct 2025 22:01:58 +0530 [thread overview]
Message-ID: <20251028163202.63905-1-avnish@linux.ibm.com> (raw)
This patch series adds a NULL check after calling grub_malloc().
Missing a failure check after calling grub_malloc() can lead to undefined
behavior. If the allocation fails and returns NULL, subsequent dereferencing
or writing to the pointer will likely result in a runtime error such as
a segmentation fault.
Patch 1/4 (0001-normal-Adding-a-grub_malloc-failure-check-in-completion-c.patch)
Patch 2/4 (0002-Adding-a-grub_malloc-failure-check-in-msdos-c.patch)
