EUVD-2026-27665

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't go past the ARM processor CPER record buffer There's a logic inside GHES/CPER to detect if the sectionlength is too small, but it doesn't detect if it is too big. Currently, if the firmware receives an ARM process...

CVE-2026-43266

The CVE-2026-43266 issue affects the Linux kernel’s ARM CPER/APEI handling: a CPER record with an oversized section_length can cause the kernel to read beyond the intended firmware buffer, leading to a large data dump and potential memory access issues. The fix adds a guard so the kernel stops at...
