CVE-2026-43333

CVE-2026-43333 (Linux kernel BPF): The vulnerability arises from direct dereference of nullable PTR_TO_BUF pointers in check_mem_access(), where PTR_TO_BUF is matched via base_type() after PTR_MAYBE_NULL stripping, allowing NULL dereferences in map iterators ctx->key/value (NULL on stop callba...

CVE-2026-43313

CVE-2026-43313 relates to a NULL-pointer dereference in the ACPI processor driver (acpi_processor_errata_piix4) of the Linux kernel. The code first assigns an IDE device to dev, then overwrites it with an ISA device using two successive pci_get_subsys lookups. If the first lookup succeeds but the...
