CVE-2022-49210

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 related to the pgd free() function. This issue arises when the system utilizes more than one page for the pgd table, and the generic implementation of pgd free() only frees one page, resulting in a memory leak. This scenario can occur, for example, when PAGE SIZE 4KB is enabled and MIPS VA BITS 48 is not enabled in a 64-bit system. The memory leak can be detected by running a shell command that continuously checks for free memory.

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