CVE-2026-63806 KVM: Replace guest-triggerable BUG_ON() in ioeventfd datamatch with get_unaligned()

In the Linux kernel, the following vulnerability has been resolved: KVM: Replace guest-triggerable BUGON in ioeventfd datamatch with getunaligned Drop a BUGON that has been reachable since it was first added, way back in 2009, and instead use getunaligned to perform potentially-unaligned accesses...

CVE-2026-63806

CVE-2026-63806 relates to the Linux kernel KVM ioeventfd datamatch bug. The issue occurs when a guest store spans multiple pages and hits MMIO on the second page, potentially triggering a datamatch IO event due to an alignment check in a 32-byte destination pointer; the code used a BUG_ON() with ...

CVE-2026-53343

A flaw was found in the Linux kernel. On ARMv5 systems configured with Kernel Address Sanitizer KASAN for virtual memory allocated VMAP stack shadow, a memory access operation could attempt to read data from an unaligned memory address. This unaligned access leads to an alignment exception, causi...
