When the isula cp command is used to copy files from a container to a host machine and the container is controlled by an attacker, the attacker can escape the container...

Copy_from_user Spectre-V1 Gadget in Linux Kernel

...

The vulnerability of the _copy_from_user() function in the lib/usercopy.c module of the Linux kernel allows a hacker to disclose protected information.

The vulnerability of the copyfromuser function in the lib/usercopy.c module of the Linux kernel is related to the characteristics of the branch prediction module’s operation. Exploiting this vulnerability allows an attacker to gain access to protected memory from a program that does not have the...

kernel: ASoC: Intel: avs: Fix potential RX buffer overflow

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Fix potential RX buffer overflow If an event caused firmware to return invalid RX size for LARGECONFIGGET, memcpyfromio could end up copying too many bytes. Fix by utilizing mint...

UBUNTU-CVE-2023-0459

Copyfromuser on 64-bit versions of the Linux kernel does not implement the uaccessbeginnospec allowing a user to bypass the "accessok" check and pass a kernel pointer to copyfromuser. This would allow an attacker to leak information. We recommend upgrading beyond...

SUSE CVE-2005-0530

Signedness error in the copyfromreadbuf function in ntty.c for Linux kernel 2.6.10 and 2.6.11rc1 allows local users to read kernel memory via a negative argument...

SUSE CVE-2006-5174

The copyfromuser function in the uaccess code in Linux kernel 2.6 before 2.6.19-rc1, when running on s390, does not properly clear a kernel buffer, which allows local user space programs to read portions of kernel memory by "appending to a file from a bad address," which triggers a fault that...

SUSE CVE-2007-1353

The setsockopt function in the L2CAP and HCI Bluetooth support in the Linux kernel before 2.4.34.3 allows context-dependent attackers to read kernel memory and obtain sensitive information via unspecified vectors involving the copyfromuser function accessing an uninitialized stack buffer...

SUSE CVE-2013-1828

The sctpgetsockoptassocstats function in net/sctp/socket.c in the Linux kernel before 3.8.4 does not validate a size value before proceeding to a copyfromuser operation, which allows local users to gain privileges via a crafted application that contains an SCTPGETASSOCSTATS getsockopt system call...

SUSE CVE-2015-1805

The 1 piperead and 2 pipewrite implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed copytouserinatomic and copyfromuserinatomic calls, which allows local users to cause a denial of service system crash or possibly gain privileges via a...

SUSE CVE-2015-3306

The modcopy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands...

SUSE CVE-2019-19053

A memory leak in the rpmsgeptdevwriteiter function in drivers/rpmsg/rpmsgchar.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service memory consumption by triggering copyfromiterfull failures, aka CID-bbe692e349e2...

SUSE CVE-2021-3492

Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copyfromuser correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service kerne...

SUSE CVE-2021-42327

dplinksettingswrite in drivers/gpu/drm/amd/display/amdgpudm/amdgpudmdebugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parsewritebufferintoparam...
