› Linux Kernel ✓patched

Linux Kernel contains a race condition vulnerability which allows concurrent writes to the same AF_ALG socket causing data to be unpredictably interleaved and creating inconsistencies in the socket's internal state. CISA added CVE-2025-39964, CVE-2026-53266, CVE-2025-39682 to the Known Exploited Vulnerabilities catalog on 2026-09-18 based on evidence of active exploitation.

› Linux Kernel ✓patched

Linux Kernel contains an unspecified vulnerability that can allow for privilege escalation via IPv6 networking subsystem. This vulnerability can impact multiple products, including but not limited to Suse, Red Hat, and other products using Linux. Added to CISA KEV on 2026-08-27.

› Linux Kernel ✓patched

Linux Kernel contains an incorrect resource transfer between spheres vulnerability that could allow for privilege escalation. Added to CISA KEV on 2026-05-01.

› Linux Kernel ✓patched

Linux Kernel contains a heap out-of-bounds write vulnerability that could allow an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space. Added to CISA KEV on 2025-10-06.

› GNU Bash ✓patched

GNU Bash contains an OS command injection vulnerability which allows remote attackers to execute arbitrary commands via a crafted environment. Added to CISA KEV on 2025-10-02.

› Sudo ✓patched

Sudo contains an inclusion of functionality from untrusted control sphere vulnerability. This vulnerability could allow local attacker to leverage sudo’s -R (--chroot) option to run arbitrary commands as root, even if they are not listed in the sudoers file. Added to CISA KEV on 2025-09-29.

› Linux Kernel ✓patched

Linux kernel contains a time-of-check time-of-use (TOCTOU) race condition vulnerability that has a high impact on confidentiality, integrity, and availability. Added to CISA KEV on 2025-09-04.

› Linux Kernel ✓patched

Linux Kernel contains an improper ownership management vulnerability, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system. Added to CISA KEV on 2025-06-17.

› Linux Kernel ✓patched

CVE-2024-53150: Linux Kernel contains an out-of-bounds read vulnerability in the USB-audio driver that allows a local, privileged attacker to obtain potentially sensitive information. CVE-2024-53197: Linux Kernel contains an out-of-bounds access vulnerability in the USB-audio driver that allows an attacker with physical access to the system to use a malicious USB device to potentially manipulate system memory, escalate privileges, or execute arbitrary code. Added to CISA KEV on 2025-04-09.

› Linux Kernel ✓patched

The Linux kernel contains a use of uninitialized resource vulnerability that allows an attacker to leak kernel memory via a specially crafted HID report. Added to CISA KEV on 2025-03-04.

› Linux Kernel ✓patched

Linux kernel contains an out-of-bounds write vulnerability in the uvc_parse_streaming component of the USB Video Class (UVC) driver that could allow for physical escalation of privilege. Added to CISA KEV on 2025-02-05.

› Linux Kernel ✓patched

Linux kernel contains a position-independent executable (PIE) stack buffer corruption vulnerability in load_elf_ binary() that allows a local attacker to escalate privileges. Added to the CISA KEV catalog on 2024-09-09. CISA lists known use in ransomware campaigns. CVE-2017-1000253 was assigned before 2024; the KEV listing came in 2024.

› Linux Kernel ✓patched

Linux kernel contains a heap-based buffer overflow vulnerability in the legacy_parse_param function in the Filesystem Context functionality. This allows an attacker to open a filesystem that does not support the Filesystem Context API and ultimately escalate privileges. Added to the CISA KEV catalog on 2024-08-21. CVE-2022-0185 was assigned before 2024; the KEV listing came in 2024.

› OpenSSH sshd (glibc-based Linux) ✓patched

Qualys found a signal handler race condition in OpenSSH's sshd on glibc-based Linux that can give an unauthenticated attacker remote code execution as root. It is a regression of CVE-2006-5051 that came back in OpenSSH 8.5p1 (October 2020). Exploitation is difficult, but Qualys counted over 14 million potentially vulnerable internet-exposed servers. Fixed in OpenSSH 9.8p1.

› Linux Kernel ✓patched

Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation. Added to the CISA KEV catalog on 2024-05-30. CISA lists known use in ransomware campaigns.

› Linux Kernel ✓patched

Linux Kernel contains a use-after-free vulnerability in the nft_object, allowing local attackers to escalate privileges. Added to the CISA KEV catalog on 2024-06-26. CVE-2022-2586 was assigned before 2024; the KEV listing came in 2024.

› GNU C Library (glibc) ld.so ✓patched

A buffer overflow in glibc's dynamic loader, triggered through the GLIBC_TUNABLES environment variable, gave local users root through SUID binaries on default installs of Fedora, Ubuntu and Debian. Cloud attackers such as Kinsing were soon using it.

› Linux Kernel ✓patched

Linux kernel contains a use-after-free vulnerability that allows for privilege escalation to gain ring0 access from the system user. Added to CISA KEV on 2023-03-30.
