|---|---|---|---|
| 2024-07-30 | CVE-2024-42138 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxsw: core_linecards: Fix double memory deallocation in case of invalid INI file In case of invalid INI file mlxsw_linecard_types_init() deallocates memory but doesn't reset pointer to NULL and returns 0. | 7.8 |
| 2024-07-30 | CVE-2024-42139 | Improper Check for Unusual or Exceptional Conditions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: Fix improper extts handling Extts events are disabled and enabled by the application ts2phc. However, in case where the driver is removed when the application is running, a specific extts event remains enabled and can cause a kernel crash. As a side effect, when the driver is reloaded and application is started again, remaining extts event for the channel from a previous run will keep firing and the message "extts on unexpected channel" might be printed to the user. To avoid that, extts events shall be disabled when PTP is released. | 5.5 |
| 2024-07-30 | CVE-2024-42140 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: riscv: kexec: Avoid deadlock in kexec crash path If the kexec crash code is called in the interrupt context, the machine_kexec_mask_interrupts() function will trigger a deadlock while trying to acquire the irqdesc spinlock and then deactivate irqchip in irq_set_irqchip_state() function. Unlike arm64, riscv only requires irq_eoi handler to complete EOI and keeping irq_set_irqchip_state() will only leave this possible deadlock without any use. | 5.5 |
| 2024-07-30 | CVE-2024-42141 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Check socket flag instead of hcon This fixes the following Smatch static checker warning: net/bluetooth/iso.c:1364 iso_sock_recvmsg() error: we previously assumed 'pi->conn->hcon' could be null (line 1359) net/bluetooth/iso.c 1347 static int iso_sock_recvmsg(struct socket *sock, struct msghdr *msg, 1348 size_t len, int flags) 1349 { 1350 struct sock *sk = sock->sk; 1351 struct iso_pinfo *pi = iso_pi(sk); 1352 1353 BT_DBG("sk %p", sk); 1354 1355 if (test_and_clear_bit(BT_SK_DEFER_SETUP, &bt_sk(sk)->flags)) { 1356 lock_sock(sk); 1357 switch (sk->sk_state) { 1358 case BT_CONNECT2: 1359 if (pi->conn->hcon && ^^^^^^^^^^^^^^ If ->hcon is NULL 1360 test_bit(HCI_CONN_PA_SYNC, &pi->conn->hcon->flags)) { 1361 iso_conn_big_sync(sk); 1362 sk->sk_state = BT_LISTEN; 1363 } else { --> 1364 iso_conn_defer_accept(pi->conn->hcon); ^^^^^^^^^^^^^^ then we're toast 1365 sk->sk_state = BT_CONFIG; 1366 } 1367 release_sock(sk); 1368 return 0; 1369 case BT_CONNECTED: 1370 if (test_bit(BT_SK_PA_SYNC, | 5.5 |
| 2024-07-30 | CVE-2024-42142 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/mlx5: E-switch, Create ingress ACL when needed Currently, ingress acl is used for three features. | 5.5 |
| 2024-07-30 | CVE-2024-42144 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/mediatek/lvts_thermal: Check NULL ptr on lvts_data Verify that lvts_data is not NULL before using it. | 5.5 |
| 2024-07-30 | CVE-2024-42145 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: IB/core: Implement a limit on UMAD receive List The existing behavior of ib_umad, which maintains received MAD packets in an unbounded list, poses a risk of uncontrolled growth. As user-space applications extract packets from this list, the rate of extraction may not match the rate of incoming packets, leading to potential list overflow. To address this, we introduce a limit to the size of the list. | 5.5 |
| 2024-07-30 | CVE-2024-42146 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/xe: Add outer runtime_pm protection to xe_live_ktest@xe_dma_buf Any kunit doing any memory access should get their own runtime_pm outer references since they don't use the standard driver API entries. | 5.5 |
| 2024-07-30 | CVE-2024-42147 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/debugfs - Fix debugfs uninit process issue During the zip probe process, the debugfs failure does not stop the probe. | 7.8 |
| 2024-07-30 | CVE-2024-42148 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bnx2x: Fix multiple UBSAN array-index-out-of-bounds Fix UBSAN warnings that occur when using a system with 32 physical cpu cores or more, or when the user defines a number of Ethernet queues greater than or equal to FP_SB_MAX_E1x using the num_queues module parameter. Currently there is a read/write out of bounds that occurs on the array "struct stats_query_entry query" present inside the "bnx2x_fw_stats_req" struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h". Looking at the definition of the "struct stats_query_entry query" array: struct stats_query_entry query[FP_SB_MAX_E1x+ BNX2X_FIRST_QUEUE_QUERY_IDX]; FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3 meaning the array has a total size of 19. Since accesses to "struct stats_query_entry query" are offset-ted by BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet queues should not exceed FP_SB_MAX_E1x (16). | 7.8 |
