CVE-2026-23407 apparmor: fix missing bounds check on DEFAULT table in verify_dfa()

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix missing bounds check on DEFAULT table in verifydfa The verifydfa function only checks DEFAULTTABLE bounds when the state is not differentially encoded. When the verification loop traverses the differential encoding...

CVE-2026-23407

The CVE-2026-23407 issue affects the Linux kernel AppArmor DFA verification. The root cause is a missing bounds check on DEFAULT_TABLE in verify_dfa(), which can read k = DEFAULT_TABLE[j] as an index without validation when traversing the differential encoding chain, allowing out-of-bounds reads/...

CVE-2026-23402

CVE-2026-23402 affects the Linux kernel KVM MMU on x86. The issue arises when overwriting a shadow-present SPTE with a different PFN, where KVM’s sanity check could allow harmful state changes in direct MMUs (i.e., MMUs without shadowed gPTEs). The problem is tracked in KVM’s mmu_set_spte path, a...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Only WARN in direct MMUs when overwriting shadow-present SPTE Adjust KVM's sanity check against overwriting a shadow-present SPTE with a another SPTE with a different target PFN to only apply to direct MMUs, i.e. on...

CVE-2026-23401

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE When installing an emulated MMIO SPTE, do so after dropping/zapping the existing SPTE if it's shadow-present. While commit a54aa15c6bda3 was right about...

CVE-2026-23401

The Linux kernel contains a vulnerability within the KVM subsystem related to x86/mmu shadow page table entry handling. Specifically, the system fails to drop/zap existing present SPTEs before installing emulated MMIO SPTEs when host userspace modifies a shadowed gPTE to switch from a memslot to ...

kernel: macvlan: fix error recovery in macvlan_common_newlink()

A use-after-free vulnerability was found in the macvlan driver. When creating a macvlan interface in source mode fails after the source MAC has been added to the hash table e.g., due to an invalid interface name, the hash entry still references the freed netdevice structure. Subsequent packets...

Ash.Type.Module.cast_input/2 atom exhaustion via unchecked Module.concat allows BEAM VM crash

Summary Ash.Type.Module.castinput/2 unconditionally creates a new Erlang atom via Module.concatvalue for any user-supplied binary string that starts with "Elixir.", before verifying whether the referenced module exists. Because Erlang atoms are never garbage-collected and the BEAM atom table has ...
