[PATCH OLK-6.6 v2] posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
by Xiongfeng Wang 06 Aug '25

06 Aug '25

From: Oleg Nesterov <oleg(a)redhat.com> stable inclusion from stable-v6.6.94 commit 2c72fe18cc5f9f1750f5bc148cf1c94c29e106ff category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICO1SY CVE: CVE-2025-38352 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f90fff1e152dedf52b932240ebbd670d83330eca upstream. If an exiting non-autoreaping task has already passed exit_notify() and calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent or debugger right after unlock_task_sighand(). If a concurrent posix_cpu_timer_del() runs at that moment, it won't be able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or lock_task_sighand() will fail. Add the tsk->exit_state check into run_posix_cpu_timers() to fix this. This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because exit_task_work() is called before exit_notify(). But the check still makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail anyway in this case.

This results in conf->r1bio_pool.wait.head pointing to a stack address. Accessing this address later can lead to a kernel panic. Example access path: raid1_reshape() { // newpool is on the stack mempool_t newpool, oldpool; // initialize newpool.wait.head to stack address mempool_init(&newpool, ...); conf->r1bio_pool = newpool; } raid1_read_request() or raid1_write_request() { alloc_r1bio() { mempool_alloc() { // if pool->alloc fails remove_element() { --pool->curr_nr; } } } } mempool_free() { if (pool->curr_nr < pool->min_nr) { // pool->wait.head is a stack address // wake_up() will try to access this invalid address // which leads to a kernel panic return; wake_up(&pool->wait); } } Fix: reinit conf->r1bio_pool.wait after assigning newpool.

[PATCH OLK-5.10] blk-mq: don't touch ->tagset in blk_mq_get_sq_hctx

From: Ming Lei <ming.lei(a)redhat.com> mainline inclusion from mainline-v5.19-rc1 commit 5d05426e2d5fd7df8afc866b78c36b37b00188b7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2VT CVE: CVE-2022-49377 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- blk_mq_run_hw_queues() could be run when there isn't queued request and after queue is cleaned up, at that time tagset is freed, because tagset lifetime is covered by driver, and often freed after blk_cleanup_queue() returns. So don't touch ->tagset for figuring out current default hctx by the mapping built in request queue, so use-after-free on tagset can be avoided. Meantime this way should be fast than retrieving mapping from tagset.

[PATCH OLK-5.10] posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

From: Oleg Nesterov <oleg(a)redhat.com> stable inclusion from stable-v5.10.239 commit c076635b3a42771ace7d276de8dc3bc76ee2ba1b category: bugfix bugzilla: 189268 CVE: CVE-2025-38352 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f90fff1e152dedf52b932240ebbd670d83330eca upstream. If an exiting non-autoreaping task has already passed exit_notify() and calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent or debugger right after unlock_task_sighand(). If a concurrent posix_cpu_timer_del() runs at that moment, it won't be able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or lock_task_sighand() will fail. Add the tsk->exit_state check into run_posix_cpu_timers() to fix this. This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because exit_task_work() is called before exit_notify(). But the check still makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail anyway in this case.

[PATCH OLK-6.6] xdp: Reset bpf_redirect_info before running a xdp's BPF prog.
by Wang Liang 05 Aug '25

05 Aug '25

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> stable inclusion from stable-v6.6.88 commit 202bca49b7f9ed3c5f5f7bb00adabea6339efe2d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC6350 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Ricardo reported a KASAN discovered use after free in v6.6-stable. The syzbot starts a BPF program via xdp_test_run_batch() which assigns ri->tgt_value via dev_hash_map_redirect() and the return code isn't XDP_REDIRECT it looks like nonsense. So the output in bpf_warn_invalid_xdp_action() appears once. Then the TUN driver runs another BPF program (on the same CPU) which returns XDP_REDIRECT without setting ri->tgt_value first. It invokes bpf_trace_printk() to print four characters and obtain the required return value. This is enough to get xdp_do_redirect() invoked which then accesses the pointer in tgt_value which might have been already deallocated. This problem does not affect upstream because since commit 401cb7dae8130 ("net: Reference bpf_redirect_info via task_struct on PREEMPT_RT.") the per-CPU variable is referenced via task's task_struct and exists on the stack during NAPI callback. Therefore it is cleared once before the first invocation and remains valid within the RCU section of the NAPI callback. Instead of performing the huge backport of the commit (plus its fix ups) here is an alternative version which only resets the variable in question prior invoking the BPF program.

[PATCH OLK-6.6 V1] i2c/designware: Fix an initialization issue
by Wang Tao 05 Aug '25

05 Aug '25

From: "Michael J. Ruhl" <michael.j.ruhl(a)intel.com> stable inclusion from stable-v6.6.97 commit 6358cb9c2a31e23b6b51bfcd7fe2b7becaf6b149 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICOXE9 CVE: CVE-2025-38380 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3d30048958e0d43425f6d4e76565e6249fa71050 upstream. The i2c_dw_xfer_init() function requires msgs and msg_write_idx from the dev context to be initialized. amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx. This could allow an out of bounds access (of msgs). Initialize msg_write_idx before calling i2c_dw_xfer_init().

[PATCH -next RFC] irqchip/gic-v5: Improve the SPI alloc efficiency
by Jinjie Ruan 04 Aug '25

04 Aug '25

If the GICv5 system has a large number of PEs and IRS components, traversing the linked list to find the irs_data corresponding to a specific SPI interrupt will be very slow. Since the maximum number of IRS nodes, the minimum and maximum SPI interrupt numbers for each IRS is known during the initialization of the IRS nodes, sort the IRS nodes by interrupt number at the initial stage. This way, when allocating SPI interrupts, we can directly perform a binary search on the irs_data using the SPI interrupt number with O(log N) complexity.

[PATCH OLK-5.10] ACPICA: Refuse to evaluate a method if arguments are missing
