Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: staging: r8712: Fix memory leak in _r8712_init_xmit_priv() In the above mentioned routine, memory is allocated in several places. If the first succeeds and a later one fails, the routine will leak memory. This patch fixes commit 2865d42c78a9 ("staging: r8712u: Add the new driver to the mainline kernel"). A potential memory leak in r8712_xmit_resource_alloc() is also addressed.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's r8712 driver, specifically in the _r8712_init_xmit_priv() function. When memory is allocated multiple times in this routine, if an early allocation succeeds but a later one fails, the previously allocated memory is not freed, causing a memory leak. The patch fixes this issue by ensuring proper memory management.

Impact Analysis

The memory leak can lead to increased memory usage over time, potentially causing system instability or degraded performance if the leaked memory accumulates. This could affect the reliability of systems running the affected Linux kernel driver.

Mitigation Strategies

To mitigate this vulnerability, update your Linux kernel to a version that includes the patch fixing the memory leak in the r8712 driver, specifically addressing the _r8712_init_xmit_priv() routine and r8712_xmit_resource_alloc(). Applying the latest kernel updates from your distribution is recommended.
