CVE-2024-46741

HighCVSS 7.8/10Last modified Aug 27, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

misc: fastrpc: Fix double free of 'buf' in error path

smatch warning: drivers/misc/fastrpc.c:1926 fastrpc_req_mmap() error: double free of 'buf'

In fastrpc_req_mmap() error path, the fastrpc buffer is freed in fastrpc_req_munmap_impl() if unmap is successful.

But in the end, there is an unconditional call to fastrpc_buf_free(). So the above case triggers the double free of fastrpc buf.
