Windows 11 is out. Is it any good for security?

Windows 11, the latest operating system OS from Microsoft, launches today, and organizations have begun asking themselves when and if they should upgrade from Windows 10 or older versions. The requirements and considerations of each organization will be different, and many things will inform the...

UBUNTU-CVE-2021-3743

An out-of-bounds OOB memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this...

CVE-2021-21790

An information disclosure vulnerability exists in the the way IOBit Advanced SystemCare Ultimate 14.2.0.220 driver handles Privileged I/O read requests. A specially crafted I/O request packet IRP can lead to privileged reads in the context of a driver which can result in sensitive information...

Iobit IOBit Advanced SystemCare is a system management utility program from the British company IOBit Iobit. The program is mainly used for scanning, repairing and optimizing the system, among other things. A security vulnerability exists in IOBit Advanced SystemCare Ultimate, which stems from an...

NVIDIA TLK 访问控制错误漏洞

Nvidia NVIDIA TLK is a scheduler from Nvidia Corporation of America for use with Trusted Firmware-A TF-A. The NVIDIA TLK suffers from an Access Control Error vulnerability that stems from the fact that the ARM® TrustZone technology, on which Trusty is based, contains a vulnerability in the access...

Linux kernel 缓冲区错误漏洞

The Linux kernel is a computer operating system kernel written in C and assembly language, compliant with the POSIX standard, and distributed under the GNU General Public License. An out-of-bounds memory write vulnerability exists in listdevices in drivers/md/dm-ioctl.c in the Multi-Device Driver...

UBUNTU-CVE-2021-31916

An out-of-bounds OOB memory write flaw was found in listdevices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user CAPSYSADMIN privilege to gain access to out-of-bounds memory leading to a system...

The vulnerability of the rtr_recvmsg function in the Linux operating system allows a hacker to obtain confidential information.

The vulnerability of the rtrrecvmsg function in the Linux operating system’s net/qrtr/qrtr.c file is related to the lack of protection for service data. Exploiting this vulnerability could allow an attacker to obtain confidential information...

CVE-2021-25369

An improper access control vulnerability in seclog file prior to SMR MAR-2021 Release 1 exposes sensitive kernel information to userspace...

Linux kernel 缓冲区错误漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. The Linux kernel suffers from a security vulnerability that stems from a memory access flaw. The vulnerability can be exploited by an attacker to gain access to out-of-bounds...

kernel: uninitialized kernel data leak in userspace coredumps

A flaw was found in the Linux kernel’s implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data...

A flaw was found in the Linux kernel’s implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data...

kernel: mishandles invalid descriptors in drivers/media/usb/gspca/xirlink_cit.c

A NULL pointer dereference flaw was found in the Xirlink camera USB driver 'xirlink-cit' in the Linux kernel. The driver mishandles invalid descriptors leading to a denial-of-service DoS. This could allow a local attacker with user privilege to crash the system or leak kernel internal information...

kernel: kernel stack information leak on s390/s390x

A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmmtimeout file. This flaw allows a local user to see the kernel data...

kernel: out-of-bounds read in in vc_do_resize function in drivers/tty/vt/vt.c

A flaw was found in the Linux kernel’s virtual console resize functionality. An attacker with local access to virtual consoles can use the virtual console resizing code to gather kernel internal data structures...
