Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved: io_uring/zctx: check chained notif contexts Send zc only links ubuf_info for requests coming from the same context. There are some ambiguous syz reports, so let’s check the assumption on notification completion. A flaw was found in the Linux kernel. A local attacker could exploit an improper handling of chained notification contexts within the io_uring/zctx component. This could lead to a denial of service (DoS) on the system.Details
