CVE-2022-48748 2024-11-04 7.5 High
In the Linux kernel, the following vulnerability has been resolved: net: bridge: vlan: fix memory leak in __allowed_ingress When using per-vlan state, if vlan snooping and stats are disabled, untagged or priority-tagged ingress frame will go to check pvid state. If the port state is forwarding and the pvid state is not learning/forwarding, untagged or priority-tagged frame will be dropped but skb memory is not freed. Should free skb when __allowed_ingress returns false.
CVE-2022-48730 2024-11-04 5.1 Medium
In the Linux kernel, the following vulnerability has been resolved: dma-buf: heaps: Fix potential spectre v1 gadget It appears like nr could be a Spectre v1 gadget as it's supplied by a user and used as an array index. Prevent the contents of kernel memory from being leaked to userspace via speculative execution by using array_index_nospec. [sumits: added fixes and cc: stable tags]
CVE-2022-48725 1 Linux 1 Linux Kernel 2024-11-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix refcounting leak in siw_create_qp() The atomic_inc() needs to be paired with an atomic_dec() on the error path.
CVE-2022-48724 1 Linux 1 Linux Kernel 2024-11-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node unconditionally allocated"). For tear down scenario, fn is only freed after fail to allocate ir_domain, though it also should be freed in case dmar_enable_qi returns error. Besides free fn, irq_domain and ir_msi_domain need to be removed as well if intel_setup_irq_remapping fails to enable queued invalidation. Improve the rewinding path by add out_free_ir_domain and out_free_fwnode lables per Baolu's suggestion.
CVE-2022-48723 1 Linux 1 Linux Kernel 2024-11-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: spi: uniphier: fix reference count leak in uniphier_spi_probe() The issue happens in several error paths in uniphier_spi_probe(). When either dma_get_slave_caps() or devm_spi_register_master() returns an error code, the function forgets to decrease the refcount of both `dma_rx` and `dma_tx` objects, which may lead to refcount leaks. Fix it by decrementing the reference count of specific objects in those error paths.
CVE-2022-48722 2024-11-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: ca8210: Stop leaking skb's Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. We then leak the skb structure. Free the skb structure upon error before returning.
CVE-2022-48720 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: net: macsec: Fix offload support for NETDEV_UNREGISTER event Current macsec netdev notify handler handles NETDEV_UNREGISTER event by releasing relevant SW resources only, this causes resources leak in case of macsec HW offload, as the underlay driver was not notified to clean it's macsec offload resources. Fix by calling the underlay driver to clean it's relevant resources by moving offload handling from macsec_dellink() to macsec_common_dellink() when handling NETDEV_UNREGISTER event.
CVE-2022-48709 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: ice: switch: fix potential memleak in ice_add_adv_recipe() When ice_add_special_words() fails, the 'rm' is not released, which will lead to a memory leak. Fix this up by going to 'err_unroll' label. Compile tested only.
CVE-2021-47624 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel E4s 2024-11-04 7.1 High
In the Linux kernel, the following vulnerability has been resolved: net/sunrpc: fix reference count leaks in rpc_sysfs_xprt_state_change The refcount leak issues take place in an error handling path. When the 3rd argument buf doesn't match with "offline", "online" or "remove", the function simply returns -EINVAL and forgets to decrease the reference count of a rpc_xprt object and a rpc_xprt_switch object increased by rpc_sysfs_xprt_kobj_get_xprt() and rpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of both unused objects. Fix this issue by jumping to the error handling path labelled with out_put when buf matches none of "offline", "online" or "remove".

CVE-2021-47553 2024-11-04 6.1 Medium
In the Linux kernel, the following vulnerability has been resolved: sched/scs: Reset task stack state in bringup_cpu() To hot unplug a CPU, the idle task on that CPU calls a few layers of C code before finally leaving the kernel. When KASAN is in use, poisoned shadow is left around for each of the active stack frames, and when shadow call stacks are in use. When shadow call stacks (SCS) are in use the task's saved SCS SP is left pointing at an arbitrary point within the task's shadow call stack. When a CPU is offlined than onlined back into the kernel, this stale state can adversely affect execution. Stale KASAN shadow can alias new stackframes and result in bogus KASAN warnings. A stale SCS SP is effectively a memory leak, and prevents a portion of the shadow call stack being used. Across a number of hotplug cycles the idle task's entire shadow call stack can become unusable. We previously fixed the KASAN issue in commit: e1b77c92981a5222 ("sched/kasan: remove stale KASAN poison after hotplug") ... by removing any stale KASAN stack poison immediately prior to onlining a CPU. Subsequently in commit: f1a0a376ca0c4ef1 ("sched/core: Initialize the idle task with preemption disabled") ... the refactoring left the KASAN and SCS cleanup in one-time idle thread initialization code rather than something invoked prior to each CPU being onlined, breaking both as above. We fixed SCS (but not KASAN) in commit: 63acd42c0d4942f7 ("sched/scs: Reset the shadow stack when idle_task_exit") ... but as this runs in the context of the idle task being offlined it's potentially fragile. To fix these consistently and more robustly, reset the SCS SP and KASAN shadow of a CPU's idle task immediately before we online that CPU in bringup_cpu(). This ensures the idle task always has a consistent state when it is running, and removes the need to so so when exiting an idle task. Whenever any thread is created, dup_task_struct() will give the task a stack which is free of KASAN shadow, and initialize the task's SCS SP, so there's no need to specially initialize either for idle thread within init_idle(), as this was only necessary to handle hotplug cycles. I've tested this on arm64 with: * gcc 11.1.0, defconfig +KASAN_INLINE, KASAN_STACK * clang 12.0.0, defconfig +KASAN_INLINE, KASAN_STACK, SHADOW_CALL_STACK ... offlining and onlining CPUS with: | while true; do | for C in /sys/devices/system/cpu/cpu*/online; do | echo 0 > $C; | echo 1 > $C; | done | done

In the Linux kernel, the following vulnerability has been resolved: mm, slub: fix potential memoryleak in kmem_cache_open() In error path, the random_seq of slub cache might be leaked. Fix this by using __kmem_cache_release() to release all the relevant resources.
CVE-2021-47426 2024-11-04 6.1 Medium
In the Linux kernel, the following vulnerability has been resolved: bpf, s390: Fix potential memory leak about jit_data Make sure to free jit_data through kfree() in the error path.
CVE-2021-47425 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: i2c: acpi: fix resource leak in reconfiguration device addition acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a reference on the adapter which is never released which will result in a reference count leak and render the adapter unremovable. Make sure to put the adapter after creating the client in the same manner that we do for OF. [wsa: fixed title]
CVE-2021-47423 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/debugfs: fix file release memory leak When using single_open() for opening, single_release() should be called, otherwise the 'op' allocated in single_open() will be leaked.
CVE-2021-47422 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/kms/nv50-: fix file release memory leak When using single_open() for opening, single_release() should be called, otherwise the 'op' allocated in single_open() will be leaked.
CVE-2021-47405 2024-11-04 5.1 Medium
In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: free raw_report buffers in usbhid_stop Free the unsent raw_report buffers when the device is removed. Fixes a memory leak reported by syzbot at: https://syzkaller.appspot.com/bug?id=7b4fa7cb1a7c2d3342a2a8a6c53371c8c418ab47
CVE-2021-47401 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: ipack: ipoctal: fix stack information leak The tty driver name is used also after registering the driver and must specifically not be allocated on the stack to avoid leaking information to user space (or triggering an oops). Drivers should not try to encode topology information in the tty device name but this one snuck in through staging without anyone noticing and another driver has since copied this malpractice. Fixing the ABI is a separate issue, but this at least plugs the security hole.
CVE-2021-47398 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Fix kernel pointer leak Pointers should be printed with %p or %px rather than cast to 'unsigned long long' and printed with %llx. Change %llx to %p to print the secured pointer.
CVE-2021-47392 2024-11-04 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Fix listener leak in rdma_cma_listen_on_all() failure If cma_listen_on_all() fails it leaves the per-device ID still on the listen_list but the state is not set to RDMA_CM_ADDR_BOUND. When the cmid is eventually destroyed cma_cancel_listens() is not called due to the wrong state, however the per-device IDs are still holding the refcount preventing the ID from being destroyed, thus deadlocking: task:rping state:D stack: 0 pid:19605 ppid: 47036 flags:0x00000084 Call Trace: __schedule+0x29a/0x780 ? free_unref_page_commit+0x9b/0x110 schedule+0x3c/0xa0 schedule_timeout+0x215/0x2b0 ? __flush_work+0x19e/0x1e0 wait_for_completion+0x8d/0xf0 _destroy_id+0x144/0x210 [rdma_cm] ucma_close_id+0x2b/0x40 [rdma_ucm] __destroy_id+0x93/0x2c0 [rdma_ucm] ? __xa_erase+0x4a/0xa0 ucma_destroy_id+0x9a/0x120 [rdma_ucm] ucma_write+0xb8/0x130 [rdma_ucm] vfs_write+0xb4/0x250 ksys_write+0xb5/0xd0 ? syscall_trace_enter.isra.19+0x123/0x190 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Ensure that cma_listen_on_all() atomically unwinds its action under the lock during error.
