CVE-2025-38274

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()<br /> <br /> fpga_mgr_test_img_load_sgt() allocates memory for sgt using<br /> kunit_kzalloc() however it does not check if the allocation failed.<br /> It then passes sgt to sg_alloc_table(), which passes it to<br /> __sg_alloc_table(). This function calls memset() on sgt in an attempt to<br /> zero it out. If the allocation fails then sgt will be NULL and the<br /> memset will trigger a NULL pointer dereference.<br /> <br /> Fix this by checking the allocation with KUNIT_ASSERT_NOT_ERR_OR_NULL().
