Background
linux-libc-dev is a package in the Linux kernel that provides the C library headers for the kernel. These headers are necessary for compiling programs that interface with the kernel. The package is widely used and is a critical component for building and running applications on Linux systems. However, a vulnerability has been discovered in the package that could lead to a double free of an anonymous device after a snapshot creation failure.
Vulnerability Detail
The vulnerability in linux-libc-dev arises when creating a snapshot. If there is an error committing the transaction during snapshot creation, a double free of an anonymous device may occur. This can result in freeing an anonymous device number that was allocated by another subsystem in the kernel or another btrfs filesystem. The issue occurs due to a flaw in the code path that handles the allocation and freeing of anonymous device numbers. An attacker could potentially exploit this vulnerability to cause a denial of service or execute arbitrary code with kernel privileges.
How To Fix
