CVE-2026-23246 1 Linux 1 Linux Kernel 2026-05-22 8.8 High
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: bounds-check link_id in ieee80211_ml_reconfiguration link_id is taken from the ML Reconfiguration element (control & 0x000f), so it can be 0..15. link_removal_timeout[] has IEEE80211_MLD_MAX_NUM_LINKS (15) elements, so index 15 is out-of-bounds. Skip subelements with link_id >= IEEE80211_MLD_MAX_NUM_LINKS to avoid a stack out-of-bounds write.
CVE-2015-8325 4 Canonical, Debian, Openbsd and 1 more 6 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 3 more 2026-05-22 7.8 High
The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable.
CVE-2026-40170 2 Ngtcp2, Tatsuhiro-t 2 Ngtcp2, Ngtcp2 2026-05-22 7.5 High
ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately upgrade, they can disable the qlog on client.
CVE-2026-36189 1 Uncrustify 1 Uncrustify 2026-05-22 6.2 Medium
Buffer Overflow vulnerability in Uncrustify Project Affected v.Uncrustify_d-0.82.0-132-bcc41cbdc and Fixed in commit 68e67b9a1435a1bb173b106fedb4a4f510972bdc allows a local attacker to cause a denial of service via the check_template.cpp, check_template function, tokenize_cleanup function, uncrustify executable components
CVE-2023-2882 1 Cbot 2 Cbot Core, Cbot Panel 2026-05-22 9.8 Critical
Generation of Incorrect Security Tokens vulnerability in CBOT Chatbot allows Token Impersonation, Privilege Abuse. This issue affects Chatbot: before Core: v4.0.3.4 Panel: v4.0.3.7.
CVE-2026-45250 1 Freebsd 1 Freebsd 2026-05-22 7.8 High
The setcred(2) system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied list exceeds the capacity of that buffer, a stack buffer overflow occurs. Because the bounds check on the supplementary groups list occurs after the kernel stack buffer has already been written, an unprivileged local user may trigger the overflow without holding any special privilege. Successful exploitation may allow an attacker to execute arbitrary code in the context of the kernel, allowing an unprivileged local user to gain elevated privileges on the affected system.
CVE-2026-8631 2 Hp, Hp Inc 2 Linux Imaging And Printing, Hp Linux Imaging And Printing Software 2026-05-21 9.8 Critical
A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This potential vulnerability may allow escalation of privileges and/or arbitrary code execution via an integer overflow in the hpcups processing path when handling crafted print data.
CVE-2026-43620 2 Rsync Project, Samba 2 Rsync, Rsync 2026-05-21 6.5 Medium
Rsync version 3.4.2 and prior contain a receiver-side out-of-bounds array read vulnerability in recv_files() in receiver.c that allows a malicious rsync server to crash the rsync client process. Attackers can exploit the vulnerability by setting CF_INC_RECURSE in compatibility flags and sending a specially crafted file list where the first sorted entry is not the leading dot directory, followed by a transfer record with ndx=0 and an iflag word without ITEM_TRANSFER, causing the receiver to read 8 bytes before the allocated pointer array and dereference an invalid pointer at an unmapped address, resulting in a deterministic SIGSEGV crash of the rsync client.
CVE-2026-43618 2 Rsync Project, Samba 2 Rsync, Rsync 2026-05-21 8.1 High
Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended buffer bounds. Attackers can exploit this vulnerability to disclose process memory contents including environment variables, passwords, heap and stack data, and library memory pointers, significantly reducing ASLR effectiveness and facilitating further exploitation.
