kernel: net: bridge: use a stable FDB dst snapshot in RCU readers

A flaw was found in the Linux kernel. Inconsistent handling of local Forwarding Database FDB entries in the bridge networking component's RCU Read-Copy-Update readers can lead to a null-pointer dereference. A local attacker could exploit this by triggering a concurrent update to an FDB entry,...

[SECURITY] Fedora 43 Update: openssh-10.0p1-10.fc43

SSH Secure SHell is a program for logging into and executing commands on a remote machine. SSH is intended to replace rlogin and rsh, and to provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forward...
