Linux · Linux Kernel · CVE-2022-49428
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A vulnerability in the Linux kernel has been identified, which can cause a kernel panic. The issue arises when the `inline dots` flag is set in a special file, such as a character, block, FIFO, or socket file, and the `f2fs` filesystem attempts to recover dot dentries. This can lead to a NULL pointer access when `f2fs add regular entry()` calls `a ops->set dirty page()`. The vulnerability can be triggered by creating a directory, mounting a fuzzed image, and listing the directory contents.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
