Title
ring-buffer: Sync IRQ works before buffer destruction
Summary
In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Sync IRQ works before buffer destruction If something was written to the buffer just before destruction, it may be possible (maybe not in a real system, but it did happen in ARCH=um with time-travel) to destroy the ringbuffer before the IRQ work ran, leading this KASAN report (or a crash without KASAN): BUG: KASAN: slab-use-after-free in irq_work_run_list+0x11a/0x13a Read of size 8 at addr 000000006d640a48 by task swapper/0 CPU: 0 PID: 0 Comm: swapper Tainted: G W O 6.3.0-rc1 #7 Stack: 60c4f20f 0c203d48 41b58ab3 60f224fc 600477fa 60f35687 60c4f20f 601273dd 00000008 6101eb00 6101eab0 615be548 Call Trace: [<60047a58>] show_stack+0x25e/0x282 [<60c609e0>] dump_stack_lvl+0x96/0xfd [<60c50d4c>] print_report+0x1a7/0x5a8 [<603078d3>] kasan_report+0xc1/0xe9 [<60308950>] __asan_report_load8_noabort+0x1b/0x1d [<60232844>] irq_work_run_list+0x11a/0x13a [<602328b4>] irq_work_tick+0x24/0x34 [<6017f9dc>] update_process_times+0x162/0x196 [<6019f335>] tick_sched_handle+0x1a4/0x1c3 [<6019fd9e>] tick_sched_timer+0x79/0x10c [<601812b9>] __hrtimer_run_queues.constprop.0+0x425/0x695 [<60182913>] hrtimer_interrupt+0x16c/0x2c4 [<600486a3>] um_timer+0x164/0x183 [...] Allocated by task 411: save_stack_trace+0x99/0xb5 stack_trace_save+0x81/0x9b kasan_save_stack+0x2d/0x54 kasan_set_track+0x34/0x3e kasan_save_alloc_info+0x25/0x28 ____kasan_kmalloc+0x8b/0x97 __kasan_kmalloc+0x10/0x12 __kmalloc+0xb2/0xe8 load_elf_phdrs+0xee/0x182 [...] The buggy address belongs to the object at 000000006d640800 which belongs to the cache kmalloc-1k of size 1024 The buggy address is located 584 bytes inside of freed 1024-byte region [000000006d640800, 000000006d640c00) Add the appropriate irq_work_sync() so the work finishes before the buffers are destroyed. Prior to the commit in the Fixes tag below, there was only a single global IRQ work, so this issue didn't exist.

No network or remote peer input is involved.\nAC:L - The attacker controls both sides of the race, arming the waiter, generating the commit that queues the irq_work, and issuing the rmdir that frees the buffer, and can retry the loop indefinitely. On architectures where arch_irq_work_raise() falls back to the timer tick (the __weak stub in kernel/irq_work.c), the queued work is not drained for up to a full jiffy, giving a millisecond-scale window.\nPR:L - An unprivileged local account is sufficient wherever tracefs access is delegated, which is standard on Android/Perfetto, ChromeOS and developer/instrumentation deployments that grant a tracing group access to /sys/kernel/tracing/instances. No real root or capability in the initial namespace is required by the code path itself, consistent with all other scored kernel/trace CVEs.\nUI:N - The attacker performs every step (arming the waiter, committing an event, removing the instance) from its own threads. No action by any other user or victim process is needed.\nS:U - The use-after-free occurs in kernel slab memory and any resulting compromise stays within the kernel\u0027s own security authority. No VM, IOMMU or sandbox boundary is crossed.\nC:H - This is a use-after-free on a kmalloc-1k object that is read back by irq_work_run_list()/irq_work_single(); combined with the hijacked work-\u003efunc(work) indirect call it yields an arbitrary kernel read primitive once the slot is reallocated with sprayed data.\nI:H - irq_work_single() writes into the freed object via atomic_set() and atomic_cmpxchg() on node.a_flags, and then calls work-\u003efunc(work) \u2014 a function pointer sourced from freed, attacker-reallocatable memory \u2014 giving control-flow hijack and arbitrary write.\nA:H - Even unexploited, the dangling irq_work node causes a slab-use-after-free that crashes the kernel from hardirq context, as shown by the KASAN splat in irq_work_run_list()/irq_work_tick() in the commit message."
