CVE-2026-43125

In the Linux kernel, the following vulnerability has been resolved: dlm: validate length in dlmsearchrsbtree The len parameter in dlmdumprsbname is not validated and comes from network messages. When it exceeds DLMRESNAMEMAXLEN, it can cause out-of-bounds write in dlmsearchrsbtree. Add length...

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...

CVE-2025-71274

Summary (CVE-2025-71274): A race in the Linux kernel rpmsg driver_override_show() can cause use-after-free of the driver_override string because reading occurs without the device_lock while the store path frees/modifies it under the lock. The fix replaces rpmsg_string_attr with explicit show/stor...
