kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in drivers/net/wireless/marvell/mwifiex/wmm.c

A flaw was found in the Linux kernel. The Marvell mwifiex driver allows a remote WiFi access point to trigger a heap-based memory buffer overflow due to an incorrect memcpy operation. The highest threat from this vulnerability is to data integrity and system availability...

kernel: kernel: DAX hugepages not considered during mremap

A flaw was found in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system...

Important: kernel-livepatch-4.14.177-139.253

Issue Overview: A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending...

Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario

A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the...

CVE-2020-10732

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...

CVE-2020-10732

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: dos in mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c

A flaw was found in the Linux kernel. The Mellanox Technologies Innova driver mishandles resource cleanup on error. An attacker, able to trigger error could use this flaw to crash the system. The highest threat from this vulnerability is to system availability...

kernel: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c

A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system...

kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS

A flaw was found in the Linux kernel’s implementation of the WiFi station handoff code. An attacker within the radio range could use this flaw to deny a valid device from joining the access point...

The vulnerability of the ext4_protect_reserved inode function (fs/ext4/block_validity.c) in the Linux kernel allows a attacker to cause a service failure.

The vulnerability of the ext4protectreserved inode function fs/ext4/blockvalidity.c in the Linux kernel involves uncontrolled resource consumption. Exploiting this vulnerability could allow an attacker to cause service failures...

kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception

A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes via a Facility Unavailable exception. An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupte...

kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow

A flaw was found in the Linux kernel's implementation of the RealTek wireless drivers WiFi-direct or WiFi peer-to-peer driver implementation. When the RealTek wireless networking hardware is configured to accept WiFi-Direct or WiFi P2P connections, an attacker within the wireless network...

kernel: Heap overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c

A flaw was found in the mwifiex implementation in the Linux kernel. A system connecting to wireless access point could be manipulated by an attacker with advanced permissions on the access point into localized memory corruption or possibly privilege escalation...

kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS

A flaw was found in the Linux kernel’s implementation of the Marvell wifi driver, which can allow a local user who has CAPNETADMIN or administrative privileges to possibly cause a Denial Of Service DOS by corrupting memory and possible code execution...

kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure

A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache indirect branch cache and Link Return Address Stack on the PowerPC platform. The flushing of these structures helps to prevent SpectreRSB like attacks which may leak information from one user process to...
