| 2024-02-28 | CVE-2021-47017 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ath10k: Fix a use after free in ath10k_htc_send_bundle In ath10k_htc_send_bundle, the bundle_skb could be freed by dev_kfree_skb_any(bundle_skb). | 7.8 |
| 2024-02-28 | CVE-2021-47025 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: Always enable the clk on resume In mtk_iommu_runtime_resume always enable the clk, even if m4u_dom is null. | 7.8 |
| 2024-02-28 | CVE-2021-47026 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-clt: destroy sysfs after removing session from active list A session can be removed dynamically by sysfs interface "remove_path" that eventually calls rtrs_clt_remove_path_from_sysfs function. | 7.8 |
| 2024-02-28 | CVE-2021-47028 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mt76: mt7915: fix txrate reporting Properly check rate_info to fix unexpected reporting.

| 2024-02-28 | CVE-2021-47039 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ataflop: potential out of bounds in do_format() The function uses "type" as an array index: q = unit[drive].disk[type]->queue; Unfortunately the bounds check on "type" isn't done until later in the function. | 7.1 |
| 2024-02-28 | CVE-2021-47040 | Classic Buffer Overflow vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: io_uring: fix overflows checks in provide buffers Colin reported before possible overflow and sign extension problems in io_provide_buffers_prep(). | 7.8 |
| 2024-02-28 | CVE-2021-47046 | Off-by-one Error vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix off by one in hdmi_14_process_transaction() The hdcp_i2c_offsets[] array did not have an entry for HDCP_MESSAGE_ID_WRITE_CONTENT_STREAM_TYPE so it led to an off by one read overflow. | 7.8 |
| 2024-02-28 | CVE-2021-47048 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: spi-zynqmp-gqspi: fix use-after-free in zynqmp_qspi_exec_op When handling op->addr, it is using the buffer "tmpbuf" which has been freed. | 7.8 |
| 2024-02-28 | CVE-2021-47049 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Use after free in __vmbus_open() The "open_info" variable is added to the &vmbus_connection.chn_msg_list, but the error handling frees "open_info" without removing it from the list. | 7.8 |
