In the Linux kernel, the following vulnerability has been resolved:

APEI/GHES: ensure that won't go past CPER allocated record

The logic at ghes_new() prevents allocating too large records, by checking if they're bigger than GHES_ESTATUS_MAX_SIZE (currently, 64KB). Yet, the allocation is done with the actual number of pages from the CPER bios table location, which can be smaller.

Yet, a bad firmware could send data with a different size, which might be bigger than the allocated memory, causing an OOPS:

WID-SEC-W-2026-1405 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um nicht spezifizierte Angriffe durchzuführen, möglicherweise Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren oder offenzulegen oder einen Denial-of-Service-Zustand zu verursachen.
