| In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Don't clone flow post action attributes second time The code already clones post action attributes in mlx5e_clone_flow_attr_for_post_act(). Creating another copy in mlx5e_tc_post_act_add() is a erroneous leftover from original implementation. Instead, assign handle->attribute to post_attr provided by the caller. Note that cloning the attribute second time is not just wasteful but also causes issues like second copy not being properly updated in neigh update code which leads to following use-after-free: Feb 21 09:02:00 c-237-177-40-045 kernel: BUG: KASAN: use-after-free in mlx5_cmd_set_fte+0x200d/0x24c0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_report+0xbb/0x1a0 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_save_stack+0x1e/0x40 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_set_track+0x21/0x30 Feb 21 09:02:00 c-237-177-40-045 kernel: __kasan_kmalloc+0x7a/0x90 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_save_stack+0x1e/0x40 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_set_track+0x21/0x30 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_save_free_info+0x2a/0x40 Feb 21 09:02:00 c-237-177-40-045 kernel: ____kasan_slab_free+0x11a/0x1b0 Feb 21 09:02:00 c-237-177-40-045 kernel: page dumped because: kasan: bad access detected Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 8833): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0xf2ff71), err(-22) Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_core 0000:08:00.0 enp8s0f0: Failed to add post action rule Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_core 0000:08:00.0: mlx5e_tc_encap_flows_add:190:(pid 8833): Failed to update flow post acts, -22 Feb 21 09:02:00 c-237-177-40-045 kernel: Call Trace: Feb 21 09:02:00 c-237-177-40-045 kernel: <TASK> Feb 21 09:02:00 c-237-177-40-045 kernel: dump_stack_lvl+0x57/0x7d Feb 21 09:02:00 c-237-177-40-045 kernel: print_report+0x170/0x471 Feb 21 09:02:00 c-237-177-40-045 kernel: ? mlx5_cmd_set_fte+0x200d/0x24c0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_report+0xbb/0x1a0 Feb 21 09:02:00 c-237-177-40-045 kernel: ? mlx5_cmd_set_fte+0x200d/0x24c0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_cmd_set_fte+0x200d/0x24c0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: ? __module_address.part.0+0x62/0x200 Feb 21 09:02:00 c-237-177-40-045 kernel: ? mlx5_cmd_stub_create_flow_table+0xd0/0xd0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: ? __raw_spin_lock_init+0x3b/0x110 Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_cmd_create_fte+0x80/0xb0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: add_rule_fg+0xe80/0x19c0 [mlx5_core] -- Feb 21 09:02:00 c-237-177-40-045 kernel: Allocated by task 13476: Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_save_stack+0x1e/0x40 Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_set_track+0x21/0x30 Feb 21 09:02:00 c-237-177-40-045 kernel: __kasan_kmalloc+0x7a/0x90 Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5_packet_reformat_alloc+0x7b/0x230 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_tc_tun_create_header_ipv4+0x977/0xf10 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_attach_encap+0x15b4/0x1e10 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: post_process_attr+0x305/0xa30 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_tc_add_fdb_flow+0x4c0/0xcf0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: __mlx5e_add_fdb_flow+0x7cf/0xe90 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_configure_flower+0xcaa/0x4b90 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_rep_setup_tc_cls_flower+0x99/0x1b0 [mlx5_core] Feb 21 09:02:00 c-237-177-40-045 kernel: mlx5e_rep_setup_tc_cb+0x133/0x1e0 [mlx5_core] -- Feb 21 09:02:00 c-237-177-40-045 kernel: Freed by task 8833: Feb 21 09:02:00 c-237-177-40-045 kernel: kasan_save_s ---truncated--- | ||||

Although this init_waitqueue_head() call will very likely complete before this kthread is created and starts running, it is possible that the calling kthread will be delayed between the calls to torture_create_kthread() and init_waitqueue_head(). In this case, the new kthread will use the waitqueue head before it is properly initialized, which is not good for the kernel's health and well-being. The above crash happened here: static inline void __add_wait_queue(...) { : if (!(wq->flags & WQ_FLAG_PRIORITY)) <=== Crash here The offset of flags from list_head entry in wait_queue_entry is -0x18. If reader_tasks[i].wq.head.next is NULL as allocated reader_task structure is zero initialized, the instruction will try to access address 0xffffffffffffffe8, which is exactly the fault address listed above. This commit therefore invokes init_waitqueue_head() before creating the kthread. | ||||

| In the Linux kernel, the following vulnerability has been resolved: nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_net Commit f5f9d4a314da ("nfsd: move reply cache initialization into nfsd startup") moved the initialization of the reply cache into nfsd startup, but didn't account for the stats counters, which can be accessed before nfsd is ever started. The result can be a NULL pointer dereference when someone accesses /proc/fs/nfsd/reply_cache_stats while nfsd is still shut down. This is a regression and a user-triggerable oops in the right situation: - non-x86_64 arch - /proc/fs/nfsd is mounted in the namespace - nfsd is not started in the namespace - unprivileged user calls "cat /proc/fs/nfsd/reply_cache_stats" Although this is easy to trigger on some arches (like aarch64), on x86_64, calling this_cpu_ptr(NULL) evidently returns a pointer to the fixed_percpu_data. That struct looks just enough like a newly initialized percpu var to allow nfsd_reply_cache_stats_show to access it without Oopsing. Move the initialization of the per-net+per-cpu reply-cache counters back into nfsd_init_net, while leaving the rest of the reply cache allocations to be done at nfsd startup time. Kudos to Eirik who did most of the legwork to track this down. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX. syzkaller found zero division error [0] in div_s64_rem() called from get_cycle_time_elapsed(), where sched->cycle_time is the divisor. We have tests in parse_taprio_schedule() so that cycle_time will never be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed(). The problem is that the types of divisor are different; cycle_time is s64, but the argument of div_s64_rem() is s32. syzkaller fed this input and 0x100000000 is cast to s32 to be 0. @TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000} We use s64 for cycle_time to cast it to ktime_t, so let's keep it and set max for cycle_time. While at it, we prevent overflow in setup_txtime() and add another test in parse_taprio_schedule() to check if cycle_time overflows. Also, we add a new tdc test case for this issue.

| In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix invalid buffer access for legacy rq The below crash can be encountered when using xdpsock in rx mode for legacy rq: the buffer gets released in the XDP_REDIRECT path, and then once again in the driver. This fix sets the flag to avoid releasing on the driver side. XSK handling of buffers for legacy rq was relying on the caller to set the skip release flag. But the referenced fix started using fragment counts for pages instead of the skip flag.

| In the Linux kernel, the following vulnerability has been resolved: net: ipa: only reset hashed tables when supported Last year, the code that manages GSI channel transactions switched from using spinlock-protected linked lists to using indexes into the ring buffer used for a channel. Recently, Google reported seeing transaction reference count underflows occasionally during shutdown. Doug Anderson found a way to reproduce the issue reliably, and bisected the issue to the commit that eliminated the linked lists and the lock. The root cause was ultimately determined to be related to unused transactions being committed as part of the modem shutdown cleanup activity. Unused transactions are not normally expected (except in error cases). The modem uses some ranges of IPA-resident memory, and whenever it shuts down we zero those ranges. In ipa_filter_reset_table() a transaction is allocated to zero modem filter table entries. If hashing is not supported, hashed table memory should not be zeroed. But currently nothing prevents that, and the result is an unused transaction. Something similar occurs when we zero routing table entries for the modem. By preventing any attempt to clear hashed tables when hashing is not supported, the reference count underflow is avoided in this case. Note that there likely remains an issue with properly freeing unused transactions (if they occur due to errors). This patch addresses only the underflows that Google originally reported. | ||||

| In the Linux kernel, the following vulnerability has been resolved: regulator: raa215300: Fix resource leak in case of error The clk_register_clkdev() allocates memory by calling vclkdev_alloc() and this memory is not freed in the error path. Similarly, resources allocated by clk_register_fixed_rate() are not freed in the error path. Fix these issues by using devm_clk_hw_register_fixed_rate() and devm_clk_hw_register_clkdev(). After this, the static variable clk is not needed. Replace it with local variable hw in probe() and drop calling clk_unregister_fixed_rate() from raa215300_rtc_unregister_device(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: amba: bus: fix refcount leak commit 5de1540b7bc4 ("drivers/amba: create devices from device tree") increases the refcount of of_node, but not releases it in amba_device_release, so there is refcount leak. By using of_node_put to avoid refcount leak. | ||||

| In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix missing mrioc->evtack_cmds initialization Commit c1af985d27da ("scsi: mpi3mr: Add Event acknowledgment logic") introduced an array mrioc->evtack_cmds but initialization of the array elements was missed. They are just zero cleared. The function mpi3mr_complete_evt_ack() refers host_tag field of the elements. Due to the zero value of the host_tag field, the function calls clear_bit() for mrico->evtack_cmds_bitmap with wrong bit index. This results in memory access to invalid address and "BUG: KASAN: use-after-free". This BUG was observed at eHBA-9600 firmware update to version 8.3.1.0. To fix it, add the missing initialization of mrioc->evtack_cmds. | ||||
