CVE-2025-38015 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix memory leak in error handling path of idxd_alloc Memory allocated for idxd is not freed if an error occurs during idxd_alloc(). To fix it, free the allocated memory in the reverse order of allocation before exiting the function in case of an error.
A memory leak vulnerability has been identified in the Linux kernel's DMA engine IDXD component. The issue arises in the error handling path of the 'idxd_allocMemory' function, where allocated memory is not properly freed if an error occurs during the allocation process. This oversight can lead to unnecessary memory consumption.
The vulnerability has been addressed in the official Linux Git repository. Users can refer to the Linux Kernel Git Repository for the patched version.
