Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not properly disabling the DMA use flag in the fsllpuart driver, which could lead to a synchronization...

SUSE CVE-2022-50362

In the Linux kernel, the following vulnerability has been resolved: dmaengine: hisilicon: Add multi-thread support for a DMA channel When we get a DMA channel and try to use it in multiple threads it will cause oops and hanging the system. % echo 100 /sys/module/dmatest/parameters/threadsperchan ...

SUSE CVE-2023-53171

In the Linux kernel, the following vulnerability has been resolved: vfio/type1: prevent underflow of lockedvm via exec When a vfio container is preserved across exec, the task does not change, but it gets a new mm with lockedvm=0, and loses the count from existing dma mappings. If the user later...

Linux Distros Unpatched Vulnerability : CVE-2023-53201

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - RDMA/bnxtre: wraparound mbox producer index Driver is not handling the wraparound of the mbox producer index correctly. Currently the wraparound happens once u3...

CVE-2023-53225

In the Linux kernel, the following vulnerability has been resolved: spi: imx: Don't skip cleanup in remove's error path Returning early in a platform driver's remove callback is wrong. In this case the dma resources are not released in the error path. this is never retried later and so this is a...

CVE-2022-50326 media: airspy: fix memory leak in airspy probe

In the Linux kernel, the following vulnerability has been resolved: media: airspy: fix memory leak in airspy probe The commit ca9dc8d06ab6 "media: airspy: respect the DMA coherency rules" moves variable buf from stack to heap, however, it only frees buf in the error handling code, missing...

CVE-2023-53244 media: pci: tw68: Fix null-ptr-deref bug in buf prepare and finish

In the Linux kernel, the following vulnerability has been resolved: media: pci: tw68: Fix null-ptr-deref bug in buf prepare and finish When the driver calls tw68riscbuffer to prepare the buffer, the function call dmaalloccoherent may fail, resulting in a empty buffer buf-cpu. Later when we free t...

CVE-2023-53244

In Linux kernel, the media: pci: tw68 driver vulnerability CVE-2023-53244 fixes a null pointer dereference in buffer handling: if dma_alloc_coherent fails during tw68_risc_buffer(), buf->cpu may be null and later accesses/free could crash. The fix adds checks on the return value of tw68_risc_b...
