The specific flaw exists within the handling of pipe buffers. This flaw allows a local user to crash or potentially escalate their privileges on the system.Ī race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring(). A local user could use this flaw to crash the system or potentially escalate their privileges on the system.Ī use-after-free flaw was found in the Linux kernel’s PLP Rose functionality in the way a user triggers a race condition by calling bind while simultaneously triggering the rose_bind() function.

The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.Ī flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function security_inode_alloc to fail with following call to function nilfs_mdt_destroy. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. In this way, the filesystem layout can be adjusted to gain root privileges through execution of available setuid-root binaries such as su or sudo.Ī buffer overflow vulnerability in the Rubrik Backup Service (RBS) Agent for Linux or Unix-based systems in Rubrik CDM 7.0.1, 7.0.1-p1, 7.0.1-p2 or 7.0.1-p3 before CDM 7.0.2-p2 could allow a local attacker to obtain root privileges by sending a crafted message to the RBS agent.Ī heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. By crafting a bogus Firejail container that is accepted by the Firejail setuid-root program as a join target, a local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS prctl is not activated, and the entered mount namespace is under the attacker's control.

This allows a malicious actor to overwrite sensitive system files and install a startup service to gain remote access to the underlaying Linux operating system with root privileges.Ī Privilege Context Switching issue was discovered in join.c in Firejail 0.9.68. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.271. Net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free.Īn authenticated attacker can upload a file with a filename including “.” and “/” to achieve the ability to upload the desired file anywhere on the filesystem. The resolution removes command formatting based on user-provided arguments. Apache NiFi Registry requires an authenticated user with authorization to read user groups in order to execute the command. Apache NiFi requires an authenticated user with authorization to modify access policies in order to execute the command. Command injection also requires an authenticated user with elevated privileges. Command injection requires ShellUserGroupProvider to be one of the enabled User Group Providers in the Authorizers configuration. The ShellUserGroupProvider is not included in the default configuration. The optional ShellUserGroupProvider in Apache NiFi 1.10.0 to 1.16.2 and Apache NiFi Registry 0.6.0 to 1.16.2 does not neutralize arguments for group resolution commands, allowing injection of operating system commands on Linux and macOS platforms. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250.
This allows Xen PV guest OS users to cause a denial of service or gain privileges.Īn issue was discovered in the Linux kernel through 5.18.9.
The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). An authenticated malicious threat actor can use this page to fully compromise the device. After performing a reverse engineering of the firmware, it was discovered that a hidden page not listed in the administration management interface allows a user to execute Linux commands on the device with root privileges. In Airspan AirSpot 5410 version 0.3.4.1-4 and under there exists a Hidden system command web page.
