https://notcve.org/view.php?id=CVE-2022-49429
26 Feb 2025 — 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.

CVE-2022-49425 – f2fs: fix dereference of stale list iterator after loop body

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: f2fs: fix dereference of stale list iterator after loop body The list iterator variable will be a bogus pointer if no break was hit. Dereferencing it (cur->page in this case) could load an out-of-bounds/undefined value making it unsafe to use that in the comparision to determine if the specific element was found. Since 'cur->page' *can* be out-ouf-bounds it cannot be guaranteed that by chance (or intention of an attacker) it matches the val... • https://git.kernel.org/stable/c/8c242db9b8c01b252290e23827163787f07e01d1 •
