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.
Affected configurations
• linux linux kernel (>= 6.2 < 6.6.51)
• linux linux kernel (>= 6.7 < 6.10.10)
• linux linux kernel 6.11
