| CVE-2026-58093 | Hig | 0.39 | 7.0 | 0.00 | Aug 26, 2026 | The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling process'… | ||
| CVE-2025-0373 | Med | 0.39 | 6.0 | 0.00 | Jan 30, 2025 | On 64-bit systems, the implementation of VOP_VPTOFH() in the cd9660, tarfs and ext2fs filesystems overflows the destination FID buffer by 4 bytes, a stack buffer overflow. A NFS server that exports a cd9660, tarfs, or ext2fs file system can be made to panic by mounting and… | ||
| CVE-2023-48795 | Med | 0.39 | 5.9 | 0.93 | Dec 18, 2023 | The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently… | ||

| CVE-2019-9494 | Med | 0.39 | 5.9 | 0.04 | Apr 17, 2019 | The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full… | ||
| CVE-2019-6111 | Med | 0.39 | 5.9 | 0.58 | Jan 31, 2019 | An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal… | ||
| CVE-2016-9042 | Med | 0.39 | 5.9 | 0.04 | Jun 4, 2018 | An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will… | ||
| CVE-2018-17156 | Med | 0.38 | 5.9 | 0.02 | Nov 28, 2018 | In FreeBSD before 11.2-STABLE(r340268) and 11.2-RELEASE-p5, due to incorrectly accounting for padding on 64-bit platforms, a buffer underwrite could occur when constructing an ICMP reply packet when using a non-standard value for the net.inet.icmp.quotelen sysctl. | ||
| CVE-2026-45252 | Med | 0.36 | 5.5 | 0.00 | May 21, 2026 | When a fusefs file system implements extended attributes, the kernel may send a FUSE_LISTXATTR message to the userspace daemon to retrieve the list of extended attributes for a given file. The FUSE protocol requires the daemon to return a packed list of NUL-terminated strings. … | ||
