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...
