| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-27 | CVE-2020-36777 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: Fix memory leak in dvb_media_device_free() dvb_media_device_free() is leaking memory. | 5.5 |
| 2024-02-27 | CVE-2021-46938 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blk_mq_tag_set for the device fails, a following device remove will cause a double free. E.g. | 7.8 |
| 2024-02-27 | CVE-2021-46939 | Improper Synchronization vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tracing: Restructure trace_clock_global() to never block It was reported that a fix to the ring buffer recursion detection would cause a hung machine when performing suspend / resume testing. | 5.5 |
| 2024-02-27 | CVE-2021-46940 | Integer Overflow or Wraparound vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tools/power turbostat: Fix offset overflow issue in index converting The idx_to_offset() function returns type int (32-bit signed), but MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number. The end result is that it hits the if (offset < 0) check in update_msr_sum() which prevents the timer callback from updating the stat in the background when long durations are used. | 5.5 |
| 2024-02-27 | CVE-2021-46941 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: core: Do core softreset when switch mode According to the programming guide, to switch mode for DRD controller, the driver needs to do the following. To switch from device to host: 1. | 5.5 |
| 2024-02-27 | CVE-2021-46942 | Unspecified vulnerability in Linux Kernel 5.12.1/5.12.2 In the Linux kernel, the following vulnerability has been resolved: io_uring: fix shared sqpoll cancellation hangs [ 736.982891] INFO: task iou-sqp-4294:4295 blocked for more than 122 seconds. [ 736.982897] Call Trace: [ 736.982901] schedule+0x68/0xe0 [ 736.982903] io_uring_cancel_sqpoll+0xdb/0x110 [ 736.982908] io_sqpoll_cancel_cb+0x24/0x30 [ 736.982911] io_run_task_work_head+0x28/0x50 [ 736.982913] io_sq_thread+0x4e3/0x720 We call io_uring_cancel_sqpoll() one by one for each ctx either in sq_thread() itself or via task works, and it's intended to cancel all requests of a specified context. | 5.5 |
| 2024-02-27 | CVE-2021-46943 | Incorrect Calculation of Buffer Size vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: staging/intel-ipu3: Fix set_fmt error handling If there in an error during a set_fmt, do not overwrite the previous sizes with the invalid config. Without this patch, v4l2-compliance ends up allocating 4GiB of RAM and causing the following OOPs [ 38.662975] ipu3-imgu 0000:00:05.0: swiotlb buffer is full (sz: 4096 bytes) [ 38.662980] DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:00:05.0 [ 38.663010] general protection fault: 0000 [#1] PREEMPT SMP | 7.8 |
| 2024-02-27 | CVE-2021-46944 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: staging/intel-ipu3: Fix memory leak in imu_fmt We are losing the reference to an allocated memory if try. | 5.5 |
| 2024-02-27 | CVE-2021-46945 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ext4: always panic when errors=panic is specified Before commit 014c9caa29d3 ("ext4: make ext4_abort() use __ext4_error()"), the following series of commands would trigger a panic: 1. | 5.5 |
| 2024-02-27 | CVE-2021-46947 | NULL Pointer Dereference vulnerability in Linux Kernel 5.12.1/5.12.2 In the Linux kernel, the following vulnerability has been resolved: sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues efx->xdp_tx_queue_count is initially initialized to num_possible_cpus() and is later used to allocate and traverse efx->xdp_tx_queues lookup array. | 5.5 |
