drm/amd/ras: Fix UMC error address allocation leak

2026-05-19T15:45:41+00:00

amdgpu_umc_handle_bad_pages() allocates err_data->err_addr before querying UMC error information. In the direct and firmware query paths, the pointer is reassigned to a fresh allocation before the original buffer is released, so the initial allocation is leaked on each handled event. Free the existing buffer before replacing it in those query paths so the function exit cleanup only owns the active allocation.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
