CVE-2026-64458

CVE-2026-64458 affects the Linux kernel’s damon subsystem (mm/damon/ops-common). The vulnerability arises from handling extreme monitoring intervals in damon_hot_score(), specifically zero or very high sampling/aggr intervals. Zero sampling interval causes a divide-by-zero in damon_max_nr_accesse...

SUSE CVE-2026-63806

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...

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-2026-45195

Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory read or write outside the permitted range of memory for the host kernel. Addresses passed to the GPU Firmware can be used by the Firmware for more privileged memory accesses...
