Linux · Linux Kernel · CVE-2022-49469
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A issue in the Linux kernel has been identified, specifically in the btrfs module. The problem occurs when certain functions, such as `btrfs qgroup inherit()`, `btrfs alloc tree block`, or `btrfs insert root()`, fail during the execution of `create subvol()`. This failure leads to a memory leak because `anon dev` is not properly freed. The error handling in `create subvol()` has been reorganized to address this issue.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
