net/mlx5: Fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list

2026-06-09T01:56:18+00:00

mlx5_query_nic_vport_mac_list() sizes its firmware command buffer using the PF's log_max_current_uc/mc_list capabilities. When querying a VF vport with a larger configured max (via devlink), the firmware response can overflow this buffer: BUG: KASAN: slab-out-of-bounds in mlx5_query_nic_vport_mac_list+0x453/0x4c0 [mlx5_core] Read of size 4 at addr ff1100013ffc8a12 by task kworker/u96:2/385 CPU: 12 UID: 0 PID: 385 Comm: kworker/u96:2 Not tainted 7.0.0-rc6+ #1 PREEMPT Hardware name: QEMU Standard PC (Q35 + ICH9, 2009) Workqueue: mlx5_esw_wq esw_vport_change_handler [mlx5_core] Call Trace: dump_stack_lvl+0x69/0xa0 print_report+0x176/0x4e4 kasan_report+0xc8/0x100 mlx5_query_nic_vport_mac_list+0x453/0x4c0 [mlx5_core] esw_update_vport_addr_list+0x2e3/0xda0 [mlx5_core] esw_vport_change_handle_locked+0xa1f/0x1060 [mlx5_core] esw_vport_change_handler+0x6a/0x90 [mlx5_core] process_one_work+0x87f/0x15e0 worker_thread+0x62b/0x1020 kthread+0x375/0x490 ret_from_fork+0x4dc/0x810 ret_from_fork_asm+0x11/0x20 Fix by querying the vport's own HCA caps to size the buffer correctly.

cfi: Include uaccess.h for get_kernel_nofault()

After commit 0652a3daa787 ("tracing: Fix CFI violation in probestub being called by tprobes"), there are many build errors when building ARCH=arm multi_v7_defconfig + CONFIG_CFI=y like: In file included from drivers/base/devres.c:17: In file included from drivers/base/trace.h:16: In file included from include/linux/tracepoint.h:23: include/linux/cfi.h:44:6: error: call to undeclared function 'get_kernel_nofault'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 44 | if (get_kernel_nofault(hash, func - cfi_get_offset())) | ^ 1 error generated. get_kernel_nofault() is called in the generic version of cfi_get_func_hash() but nothing ensures uaccess.h is always included for a proper expansion and prototype. Include uaccess.h in cfi.h to clear up the errors.

Pull tracing fix from Steven Rostedt: - Fix CFI violation in probestub function The probestub is a function to allow tprobes to hook to a tracepoint to gain access to its parameters. The function itself is only referenced by the tracepoint structure which lives in the __tracepoint section. objtool explicitly ignores that section and when processing functions in the kernel, if it detects one that has no references it will seal it to have its ENDBR stripped on boot up. This means the probstub function will have its ENDBR stripped and if a tprobe is attached to it with IBT enabled, it will go *boom*. * tag 'trace-v7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix CFI violation in probestub being called by tprobes

tracing: Fix CFI violation in probestub being called by tprobes

2026-06-04T09:03:56+00:00

The probestub is a function to allow tprobes to hook to a tracepoint to gain access to its parameters. The function itself is only referenced by the tracepoint structure which lives in the __tracepoint section. objtool explicitly ignores that section and when processing functions in the kernel, if it detects one that has no references it will seal it to have its ENDBR stripped on boot up. This means when a tprobe is attached to the sched_wakeup tracepoint, when it is triggered it will call __probestub_sched_wakeup and due to the missing ENDBR on a CFI-enabled machine it will take a #CP exception. Fix this by adding CFI_NOSEAL annotation to probestub declaration.

rseq: Fix using an uninitialized stack variable in rseq_exit_user_update()

2026-06-02T10:41:15+00:00

There is an bug in which an uninitialized stack variable is used in rseq_exit_user_update() as reported by syzbot: BUG: KMSAN: kernel-infoleak in rseq_set_ids_get_csaddr include/linux/rseq_entry.h:502 [inline] The local variable: struct rseq_ids ids = { .cpu_id = task_cpu(t), .mm_cid = task_mm_cid(t), .node_id = cpu_to_node(ids.cpu_id), }; According to the C standard, the evaluation order of expressions in an initializer list is indeterminately sequenced. The compiler (Clang, in this KMSAN build) evaluates `cpu_to_node(ids.cpu_id)` *before* `ids.cpu_id` is initialized with `task_cpu(t)`. This is fixed by moving the assignment of ids.node_id outside the structure initialization.
