CVE-2021-46982 f2fs: compress: fix race condition of overwrite vs truncate
In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix race condition of overwrite vs truncate posfsstress testcase complains a panic as belew: ------------ cut here ------------ kernel BUG at fs/f2fs/compress.c:1082! invalid opcode: 0000 1 SMP PTI CPU: 4 PID:...
CVE-2021-46982
CVE-2021-46982 relates to the Linux kernel’s f2fs compress path. A race between truncate and overwrite can leave a reference on a page, causing find_lock_page to return NULL after truncation. Root cause involves prepare_compress_overwrite, f2fs_pagecache_get_page, and subsequent truncate_setsize/...

CVE-2021-46920
A flaw was found in the Linux Kernel. The current code blindly writes over the SWERR and OVERFLOW bits. Write back the bits read so that the driver avoids clobbering the OVERFLOW bit that comes after the register is read...
MikroTik RouterOS Improper Access Control (CVE-2021-27221)
MikroTik RouterOS 6.47.9 allows remote authenticated ftp users to create or overwrite arbitrary .rsc files via the /export command. NOTE: the vendor's position is that this is intended behavior because of how user policies work This plugin only works with Tenable.ot. Please visit...
Medium: unbound
Issue Overview: NLnet Labs Unbound, up to and including version 1.16.1 is vulnerable to a novel type of the "ghost domain names" attack. The vulnerability works by targeting an Unbound instance. Unbound is queried for a subdomain of a rogue domain name. The rogue nameserver returns delegation...
Dell Unity Command Injection Vulnerability (CNVD-2024-09156)
Dell Unity is a unified hybrid storage array for general purpose workloads both locally and in the cloud. A command injection vulnerability exists in Dell Unity, which can be exploited by a local attacker to overwrite arbitrary files on a file system using root privileges...
CVE-2022-23092
The implementation of lib9p's handling of RWALK messages was missing a bounds check needed when unpacking the message contents. The missing check means that the receipt of a specially crafted message will cause lib9p to overwrite unrelated memory. The bug can be triggered by a malicious bhyve gue...

CVE-2022-23088
The 802.11 beacon handling routine failed to validate the length of an IEEE 802.11s Mesh ID before copying it to a heap-allocated buffer. While a FreeBSD Wi-Fi client is in scanning mode i.e., not associated with a SSID a malicious beacon frame may overwrite kernel memory, leading to remote code...
CVE-2022-23087
The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload "TSO". The e1000 device model uses an on-stack buffer to generat...

CVE-2022-23087
The CVE-2022-23087 issue affects the e1000 device emulation in bhyve on FreeBSD, where the device model uses an on‑stack buffer to modify transmitted packets. When checksum offload is requested, a guest‑provided checksum offset is accepted without validation for certain packet types, enabling a m...
