| 2025-03-27 | CVE-2023-53011 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: stmmac: enable all safety features by default In the original implementation of dwmac5 commit 8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default. Later it seems some implementations didn't have support for all the features, so in commit 5ac712dcdfef ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features. The problem is that only certain platforms were given that software support. | 5.5 |
| 2025-03-27 | CVE-2023-53013 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ptdma: pt_core_execute_cmd() should use spinlock The interrupt handler (pt_core_irq_handler()) of the ptdma driver can be called from interrupt context. | 5.5 |
| 2025-03-27 | CVE-2023-53014 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dmaengine: tegra: Fix memory leak in terminate_all() Terminate vdesc when terminating an ongoing transfer. This will ensure that the vdesc is present in the desc_terminated list The descriptor will be freed later in desc_free_list(). This fixes the memory leaks which can happen when terminating an ongoing transfer. | 5.5 |
| 2025-03-27 | CVE-2023-53015 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: betop: check shape of output reports betopff_init() only checks the total sum of the report counts for each report field to be at least 4, but hid_betopff_play() expects 4 report fields. A device advertising an output report with one field and 4 report counts would pass the check but crash the kernel with a NULL pointer dereference in hid_betopff_play(). | 5.5 |
| 2025-03-27 | CVE-2023-53016 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix possible deadlock in rfcomm_sk_state_change syzbot reports a possible deadlock in rfcomm_sk_state_change [1]. While rfcomm_sock_connect acquires the sk lock and waits for the rfcomm lock, rfcomm_sock_release could have the rfcomm lock and hit a deadlock for acquiring the sk lock. Here's a simplified flow: rfcomm_sock_connect: lock_sock(sk) rfcomm_dlc_open: rfcomm_lock() rfcomm_sock_release: rfcomm_sock_shutdown: rfcomm_lock() __rfcomm_dlc_close: rfcomm_k_state_change: lock_sock(sk) This patch drops the sk lock before calling rfcomm_dlc_open to avoid the possible deadlock and holds sk's reference count to prevent use-after-free after rfcomm_dlc_open completes. | 5.5 |
| 2025-03-27 | CVE-2023-53017 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: fix memory leak in hci_update_adv_data() When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR to pass the instance to callback so no memory needs to be allocated. | 5.5 |
| 2025-03-27 | CVE-2023-53018 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: Fix memory leaks When hci_cmd_sync_queue() failed in hci_le_terminate_big() or hci_le_big_terminate(), the memory pointed by variable d is not freed, which will cause memory leak. | 5.5 |
| 2025-03-27 | CVE-2023-53020 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: l2tp: close all race conditions in l2tp_tunnel_register() The code in l2tp_tunnel_register() is racy in several ways: 1. | 4.7 |
| 2025-03-27 | CVE-2023-53022 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: enetc: avoid deadlock in enetc_tx_onestep_tstamp() This lockdep splat says it better than I could: ================================ WARNING: inconsistent lock state 6.2.0-rc2-07010-ga9b9500ffaac-dirty #967 Not tainted -------------------------------- inconsistent {IN-SOFTIRQ-W} -> {SOFTIRQ-ON-W} usage. kworker/1:3/179 [HC0[0]:SC0[0]:HE1:SE1] takes: ffff3ec4036ce098 (_xmit_ETHER#2){+.?.}-{3:3}, at: netif_freeze_queues+0x5c/0xc0 {IN-SOFTIRQ-W} state was registered at: _raw_spin_lock+0x5c/0xc0 sch_direct_xmit+0x148/0x37c __dev_queue_xmit+0x528/0x111c ip6_finish_output2+0x5ec/0xb7c ip6_finish_output+0x240/0x3f0 ip6_output+0x78/0x360 ndisc_send_skb+0x33c/0x85c ndisc_send_rs+0x54/0x12c addrconf_rs_timer+0x154/0x260 call_timer_fn+0xb8/0x3a0 __run_timers.part.0+0x214/0x26c run_timer_softirq+0x3c/0x74 __do_softirq+0x14c/0x5d8 ____do_softirq+0x10/0x20 call_on_irq_stack+0x2c/0x5c do_softirq_own_stack+0x1c/0x30 __irq_exit_rcu+0x168/0x1a0 irq_exit_rcu+0x10/0x40 el1_interrupt+0x38/0x64 irq event stamp: 7825 hardirqs last enabled at (7825): [<ffffdf1f7200cae4>] exit_to_kernel_mode+0x34/0x130 hardirqs last disabled at (7823): [<ffffdf1f708105f0>] __do_softirq+0x550/0x5d8 softirqs last enabled at (7824): [<ffffdf1f7081050c>] __do_softirq+0x46c/0x5d8 softirqs last disabled at (7811): [<ffffdf1f708166e0>] ____do_softirq+0x10/0x20 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(_xmit_ETHER#2); <Interrupt> lock(_xmit_ETHER#2); *** DEADLOCK *** 3 locks held by kworker/1:3/179: #0: ffff3ec400004748 ((wq_completion)events){+.+.}-{0:0}, at: process_one_work+0x1f4/0x6c0 #1: ffff80000a0bbdc8 ((work_completion)(&priv->tx_onestep_tstamp)){+.+.}-{0:0}, at: process_one_work+0x1f4/0x6c0 #2: ffff3ec4036cd438 (&dev->tx_global_lock){+.+.}-{3:3}, at: netif_tx_lock+0x1c/0x34 Workqueue: events enetc_tx_onestep_tstamp Call trace: print_usage_bug.part.0+0x208/0x22c mark_lock+0x7f0/0x8b0 __lock_acquire+0x7c4/0x1ce0 lock_acquire.part.0+0xe0/0x220 lock_acquire+0x68/0x84 _raw_spin_lock+0x5c/0xc0 netif_freeze_queues+0x5c/0xc0 netif_tx_lock+0x24/0x34 enetc_tx_onestep_tstamp+0x20/0x100 process_one_work+0x28c/0x6c0 worker_thread+0x74/0x450 kthread+0x118/0x11c but I'll say it anyway: the enetc_tx_onestep_tstamp() work item runs in process context, therefore with softirqs enabled (i.o.w., it can be interrupted by a softirq). | 5.5 |
| 2025-03-27 | CVE-2023-53026 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix ib block iterator counter overflow When registering a new DMA MR after selecting the best aligned page size for it, we iterate over the given sglist to split each entry to smaller, aligned to the selected page size, DMA blocks. In given circumstances where the sg entry and page size fit certain sizes and the sg entry is not aligned to the selected page size, the total size of the aligned pages we need to cover the sg entry is >= 4GB. Under this circumstances, while iterating page aligned blocks, the counter responsible for counting how much we advanced from the start of the sg entry is overflowed because its type is u32 and we pass 4GB in size. | 5.5 |
