Linux Kernel Memory Leak Vulnerability in libwx Component

A memory leak vulnerability has been identified in the Linux kernel's libwx component. This issue arises in the wx_setup_rx_resources function, where the wx_alloc_page_pool function's failure does not trigger a release of the allocated DMA buffer. The vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability leads to a memory leak, where allocated DMA buffers are not properly released, potentially causing increased memory usage and degradation of system performance over time.

Remediation

Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel official website.
