CVE-2025-68759

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

Description A memory leak issue was identified and resolved in the Linux kernel’s wifi subsystem, specifically within the rtl8180 init rx ring() function. This function allocates memory for skb packets and DMA allocations in a loop. If an allocation fails during this process, previously successful allocations were not freed before exiting the function, leading to a memory leak. The fix involves jumping to an error handling label (err free rings) to ensure all allocated resources are released. The code was modified to avoid a double free by setting the priv->rx buf entry to null after freeing the memory.

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