CVE-2026-43167

CVE-2026-43167 relates to the Linux kernel xfrm subsystem where a reference-count leak in xfrm_state occurs when a network device is unregistered. The issue stems from an IPsec hardware-offload API change (commit d77e38e612a0) that made xfrm_dev_unregister() a no-op, even though xfrm_dev_state_ad...

CVE-2026-43125

CVE-2026-43125 affects the Linux kernel dlm module. The vulnerability stems from unvalidated length in dlm_dump_rsb_name() coming from network messages, allowing an out-of-bounds write in dlm_search_rsb_tree() when the length exceeds DLM_RESNAME_MAXLEN. This could enable denial of service and, in...
