Vulnerability from fkie_nvd - Published: 2025-02-26 07:01 - Updated: 2025-10-22 17:27
Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Prevent panic when SDMA is disabled
If the hfi1 module is loaded with HFI1_CAP_SDMA off, a call to
hfi1_write_iter() will dereference a NULL pointer and panic. A typical
stack frame is:
sdma_select_user_engine [hfi1]
hfi1_user_sdma_process_request [hfi1]
hfi1_write_iter [hfi1]
do_iter_readv_writev
do_iter_write
vfs_writev
do_writev
do_syscall_64
The fix is to test for SDMA in hfi1_write_iter() and fail the I/O with
EINVAL.
