Background
linux-libc-dev is a package in the Debian operating system that provides the C library development files for the Linux kernel. It is an essential component for compiling and building applications on Debian. The linux-libc-dev package contains header files and libraries necessary for developing programs that interact with the Linux kernel. This vulnerability affects the linux-libc-dev package version 6.1.90-1.
Vulnerability Detail
