| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to the
dm cache component of the Linux kernel, specifically with the flush work() function. It may cause an unexpected WARN ON when cache creation fails due to the destruction of an uninitialized delayed work waker in the error path of cache create(). This can occur, for example, on a superblock checksum error. The problem is associated with the use of memory after it has been freed, which could potentially allow an attacker to cause a denial of service.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
