CVE-2024-41010

CVE-2024-41010 concerns a Linux kernel vulnerability in the BPF tcx_entry management for old-style ingress/clsact qdiscs. The issue is a use-after-free caused by releasing tcx_entry too early when a shared tc block is replaced, enabling a local attacker to trigger a UAF through a specific qdisc s...

SUSE CVE-2022-3586

A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the schsfb enqueue function used the socket buffer SKB cb field after the same SKB had been enqueued and freed into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing...
