| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-05-21 | CVE-2021-47334 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: misc/libmasm/module: Fix two use after free in ibmasm_init_one In ibmasm_init_one, it calls ibmasm_init_remote_input_dev(). Inside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are allocated by input_allocate_device(), and assigned to sp->remote.mouse_dev and sp->remote.keybd_dev respectively. In the err_free_devices error branch of ibmasm_init_one, mouse_dev and keybd_dev are freed by input_free_device(), and return error. | 7.8 |
| 2024-05-21 | CVE-2021-47345 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Fix rdma_resolve_route() memory leak Fix a memory leak when "mda_resolve_route() is called more than once on the same "rdma_cm_id". This is possible if cma_query_handler() triggers the RDMA_CM_EVENT_ROUTE_ERROR flow which puts the state machine back and allows rdma_resolve_route() to be called again. | 5.5 |
| 2024-05-21 | CVE-2021-47353 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: udf: Fix NULL pointer dereference in udf_symlink function In function udf_symlink, epos.bh is assigned with the value returned by udf_tgetblk. | 5.5 |
| 2024-05-21 | CVE-2021-47355 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: atm: nicstar: Fix possible use-after-free in nicstar_cleanup() This module's remove path calls del_timer(). | 7.8 |
| 2024-05-21 | CVE-2021-47357 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: atm: iphase: fix possible use-after-free in ia_module_exit() This module's remove path calls del_timer(). | 7.8 |
| 2024-05-20 | CVE-2024-35972 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix possible memory leak in bnxt_rdma_aux_device_init() If ulp = kzalloc() fails, the allocated edev will leak because it is not properly assigned and the cleanup path will not be able to free it. Fix it by assigning it properly immediately after allocation. | 5.5 |
| 2024-05-20 | CVE-2024-35978 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix memory leak in hci_req_sync_complete() In 'hci_req_sync_complete()', always free the previous sync request state before assigning reference to a new one. | 5.5 |
| 2024-05-20 | CVE-2024-35981 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: virtio_net: Do not send RSS key if it is not supported There is a bug when setting the RSS options in virtio_net that can break the whole machine, getting the kernel into an infinite loop. Running the following command in any QEMU virtual machine with virtionet will reproduce this problem: # ethtool -X eth0 hfunc toeplitz This is how the problem happens: 1) ethtool_set_rxfh() calls virtnet_set_rxfh() 2) virtnet_set_rxfh() calls virtnet_commit_rss_command() 3) virtnet_commit_rss_command() populates 4 entries for the rss scatter-gather 4) Since the command above does not have a key, then the last scatter-gatter entry will be zeroed, since rss_key_size == 0. sg_buf_size = vi->rss_key_size; 5) This buffer is passed to qemu, but qemu is not happy with a buffer with zero length, and do the following in virtqueue_map_desc() (QEMU function): if (!sz) { virtio_error(vdev, "virtio: zero sized buffers are not allowed"); 6) virtio_error() (also QEMU function) set the device as broken vdev->broken = true; 7) Qemu bails out, and do not repond this crazy kernel. 8) The kernel is waiting for the response to come back (function virtnet_send_command()) 9) The kernel is waiting doing the following : while (!virtqueue_get_buf(vi->cvq, &tmp) && !virtqueue_is_broken(vi->cvq)) cpu_relax(); 10) None of the following functions above is true, thus, the kernel loops here forever. | 5.5 |
| 2024-05-20 | CVE-2024-35982 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: batman-adv: Avoid infinite loop trying to resize local TT If the MTU of one of an attached interface becomes too small to transmit the local translation table then it must be resized to fit inside all fragments (when enabled) or a single packet. But if the MTU becomes too low to transmit even the header + the VLAN specific part then the resizing of the local TT will never succeed. | 5.5 |
| 2024-05-20 | CVE-2024-35984 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: fix NULL function pointer dereference Baruch reported an OOPS when using the designware controller as target only. | 5.5 |
