CVE-2026-89561

CVE-2026-89561 is a NULL pointer dereference in the Linux kernel's IPv6 RPL (Routing Protocol for Low-Power and Lossy Networks) implementation. The function ipv6_rpl_srh_rcv() dereferences idev obtained from __in6_dev_get() without a NULL check when reading idev->cnf.rpl_seg_enabled. The race ...

CVE-2026-89559

CVE-2026-89559 affects the Linux kernel's libnvdimm/labels subsystem. The nslot field (a u32 read from DIMM label storage or via ND_CMD_SET_CONFIG_DATA) is multiplied by label_size in __nd_label_validate(). Because sizeof_namespace_label() returns unsigned, the product is evaluated in 32-bit and ...
