VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A memory leak issue has been identified in the Linux kernel, specifically in the dmi-sysfs firmware component. The problem arises when the kobject init and add() function fails but still takes a reference, leading to a memory leak. According to the documentation, kobject put() must be called to properly clean up the associated memory when kobject init and add() returns an error. This issue has been resolved by adding the necessary call to kobject put().
Recommendations For the affected Linux kernel versions, the issue can be resolved by applying the fix that calls kobject put() when kobject init and add() fails. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
