Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dlm: Length validation in dlmsearchrsbtree was added. The len parameter in dlmdumprsbname is not validated and comes from network messages. When this parameter exceeds DLMRESNAMEMAXLEN, it may cause an out-of-bounds write in...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...
