First published: Mon Dec 12 2022(Updated: )

A flaw stack overflow in the Linux Kernel found. If user have access to SYSCTL (dynamically changing certain kernel parameters and variables), then can provide incorrect input to the function do_proc_dointvec leading to system crash or potentially privileges escalation. Known example of such incorrect input by local user for the /proc/sys/net/ipv4/tcp_rmem , but it could be other situations when this function being used.
