| Vetor | AV:N/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel version 5.0.21
Description
The issue is related to a NULL pointer dereference in the
f2fs recover fsync data function in the Linux kernel, specifically when mounting a crafted f2fs filesystem image. This is connected to F2FS P SB in fs/f2fs/f2fs.h. The vulnerability can be exploited to gain unauthorized access to protected information using a mounted f2fs filesystem image.Recommendations
For Linux kernel version 5.0.21, consider disabling the
f2fs recover fsync data function as a temporary workaround until a patch is available. Restrict access to the f2fs filesystem to minimize the risk of exploitation. Avoid using crafted f2fs filesystem images until the issue is resolved.Exploit
