DEBIAN-CVE-2021-3491

The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was...

kernel: heap buffer overflow in the iSCSI subsystem

A flaw was found in the Linux kernel. A heap buffer overflow in the iSCSI subsystem is triggered by setting an iSCSI string attribute to a value larger than one page and then trying to read it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system...

Amazon Linux 2 : kernel (ALAS-2021-1600)

The version of kernel installed on the remote host is prior to 4.14.219-161.340. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1600 advisory. 2024-05-23: CVE-2023-1390 was added to this advisory. A use-after-free flaw was found in kernel/trace/ringbuffer.c...

CVE-2020-7460

In FreeBSD 12.1-STABLE before r363918, 12.1-RELEASE before p8, 11.4-STABLE before r363919, 11.4-RELEASE before p2, and 11.3-RELEASE before p12, the sendmsg system call in the compat32 subsystem on 64-bit platforms has a time-of-check to time-of-use vulnerability allowing a mailcious userspace...

kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver

A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This...

CVE-2020-10829

An issue was discovered on Samsung mobile devices with O8.0, P9.0, and Q10.0 Broadcom chipsets software. A kernel driver heap overflow leads to arbitrary code execution. The Samsung ID is SVE-2019-15880 March 2020...

kernel: heap overflow in marvell/mwifiex/tdls.c

A heap overflow flaw was found in the Linux kernel's Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If cod...

kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in marvell/mwifiex/scan.c

A flaw was found in the Linux kernel's Marvell wifi chip driver. A heap overflow in mwifiexupdatebssdescwithie function in marvell/mwifiex/scan.c allows remote attackers to cause a denial of servicesystem crash or execute arbitrary code...

kernel: Heap address information leak while using L2CAP_GET_CONF_OPT

A flaw was found in the Linux kernel's implementation of Logical Link Control and Adaptation Protocol L2CAP, part of the Bluetooth stack. An attacker, within the range of standard Bluetooth transmissions, can create and send a specially crafted packet. The response to this specially crafted packe...

kernel: Heap address information leak while using L2CAP_PARSE_CONF_RSP

A flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol L2CAP, part of the Bluetooth stack in the l2capparseconfrsp and l2capparseconfreq functions. An attacker with physical access within the range of standard Bluetooth transmission can create a...

CVE-2017-7184

Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation...
