Summary

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix oob write in trace_seq_to_buffer() syzbot reported this bug: ================================================================== BUG: KASAN: slab-out-of-bounds in trace_seq_to_buffer kernel/trace/trace.c:1830 [inline] BUG: KASAN: slab-out-of-bounds in tracing_splice_read_pipe+0x6be/0xdd0 kernel/trace/trace.c:6822 Write of size 4507 at addr ffff888032b6b000 by task syz.2.320/7260 CPU: 1 UID: 0 PID: 7260 Comm: syz.2.320 Not tainted 6.15.0-rc1-syzkaller-00301-g3bde70a2c827 #0 PREEMPT(full) Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 02/12/2025 Call Trace: <TASK> __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0x116/0x1f0 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:408 [inline] print_report+0xc3/0x670 mm/kasan/report.c:521 kasan_report+0xe0/0x110 mm/kasan/report.c:634 check_region_inline mm/kasan/generic.c:183 [inline] kasan_check_range+0xef/0x1a0 mm/kasan/generic.c:189 __asan_memcpy+0x3c/0x60 mm/kasan/shadow.c:106 trace_seq_to_buffer kernel/trace/trace.c:1830 [inline] tracing_splice_read_pipe+0x6be/0xdd0 kernel/trace/trace.c:6822 .... ================================================================== It has been reported that trace_seq_to_buffer() tries to copy more data than PAGE_SIZE to buf. Therefore, to prevent this, we should use the smaller of trace_seq_used(&iter->seq) and PAGE_SIZE as an argument.

There is no network-facing path to `tracing_splice_read_pipe()`.\nAC:L - The overflow is deterministic and fully attacker-driven: generate more than one page of formatted trace output (a single ~4096-byte `trace_marker` record, or simply let `tracing_fill_pipe_page()` accumulate events up to the 8K trace_seq limit) and then splice from trace_pipe. No race, no memory-layout luck, and no non-default kernel config is needed.\nPR:L - `tracing_open_pipe()` contains no capability check whatsoever \u2014 reachability is gated only by DAC on the tracefs inode, and tracefs exposes `uid=`/`gid=`/`mode=` mount parameters precisely so a non-root group can be granted ftrace access. Android grants `shell`/atrace/Perfetto (`AID_READTRACEFS`) access to trace_pipe and distro/CI/observability deployments commonly chgrp the tracing tree, so an unprivileged local account reaches this path.\nUI:N - The attacker performs every step (open, generate trace data, splice) from its own process. No victim action or interaction is required.\nS:U - The out-of-bounds write and disclosure occur within kernel memory under the same security authority as the kernel itself; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Before the fix `spd.partial[i].len` was set to `trace_seq_used()` (up to ~8152) for a 4096-byte page, so `splice_to_pipe()` returns a pipe buffer that lets userspace read roughly 4KB of adjacent kernel memory directly \u2014 an arbitrary-content kernel infoleak, on top of the OOB write\u0027s exploitability for further disclosure.\nI:H - `trace_seq_to_buffer()` memcpy\u0027s up to ~4056 bytes past the end of a freshly allocated order-0 page into adjacent kernel memory, with largely attacker-chosen content (e.g. arbitrary bytes injected via `trace_marker`). A ~4KB controlled linear-map overflow with attacker-groomable neighbours is a strong write primitive suitable for control-flow hijacking.\nA:H - The overflow corrupts whatever kernel memory follows the page, reliably producing KASAN splats, oopses, or panics as reported by syzbot, and it can be re-triggered at will."
