CVE-2026-98740 EDAC/altera: Drop __init from ECC setup paths for re-probe safety

In the Linux kernel, the following vulnerability has been resolved: EDAC/altera: Drop init from ECC setup paths for re-probe safety Sashiko reports: "Does suppressing sysfs unbinding fully prevent the execution of freed init memory? If altrsysmgrregmaplookupbyphandle returns -EPROBEDEFER, the pro...

CVE-2026-98740

The Linux kernel contains a vulnerability where several a10 EDAC .setup callbacks (including sdmmc, ethernet, nand, dma, usb, and qspi) and their helpers were incorrectly marked with init . This allows for potential dereferencing of freed memory if a probe is deferred via -EPROBE_DEFER or trigge...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Bail from shadow walks if the root is invalid or a dummy When walking shadow page tables, immediately terminate the walk if the root is a "dummy" root, i.e. a root whose top-level page table is backed by the zero...

EUVD-2026-103971

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Bail from shadow walks if the root is invalid or a dummy When walking shadow page tables, immediately terminate the walk if the root is a "dummy" root, i.e. a root whose top-level page table is backed by the zero...

CVE-2026-98717

The Linux kernel KVM component is vulnerable to a NULL pointer dereference within the x86/mmu shadow page table walking logic. The issue occurs when a race condition exists between memslot creation and a stage-2 page fault (EPT violation or #NPF) from L2. If the root is a "dummy" root—where the t...
