kernel: serial: sprd: Fix DMA buffer leak issue

A flaw was found in the serial: sprd driver in the Linux kernel where a DMA buffer allocated during driver probe was not released when probe returned failure. This results in a memory leak that, under repeated probe failure conditions, could cause elevated kernel memory usage and potential resour...

UBUNTU-CVE-2022-49019

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: nixge: fix NULL dereference In function nixgehwdmabdrelease dereference of NULL pointer priv-rxbdv is possible for the case of its allocation failure in nixgehwdmabdinit. Move for loop with priv-rxbdv dereference...

The vulnerability of the cma_heap_vm_fault() function in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the cmaheapvmfault function in the drivers/dma-buf/heaps/cmaheap.c module of the Linux kernel is related to an error in calculating the boundaries of the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

DEBIAN-CVE-2024-46709

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix prime with external buffers Make sure that for external buffers mapping goes through the dmabuf interface instead of trying to access pages directly. External buffers might not provide direct access to...

SUSE CVE-2024-42146

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Add outer runtimepm protection to xelivektest@xedmabuf Any kunit doing any memory access should get their own runtimepm outer references since they don't use the standard driver API entries. In special this dmabuf from th...

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 the fact that any kunit in the drm/xe module that uses dmabuf for memory accesses should get its own externa...

SUSE CVE-2022-48821

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: avoid double fput on failed usercopy If the copy back to userland fails for the FASTRPCIOCTLALLOCDMABUFF ioctl, we shouldn't assume that 'buf-dmabuf' is still valid. In fact, dmabuffd called fdinstall before, i.e...

CVE-2021-47477

CVE-2021-47477 is documented in connected advisories as a Linux kernel issue affecting comedi: dt9812. The root cause is DMA buffers being allocated on the stack for USB transfers; the fix allocates proper transfer buffers in the command helpers and returns an error on short transfers instead of ...
