Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A issue in the Linux kernel has been identified where a stale list iterator could be dereferenced after a loop, potentially leading to out-of-bounds or undefined values being loaded. This could result in unsafe comparisons, making it difficult to determine if a specific element was found. The problem arises when 'cur->page' is dereferenced and its value is used for comparison, as it may match the value of 'page' by chance or intention, even if the correct element was not found.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
