CVE-2023-3212 5 Debian, Fedoraproject, Linux and 2 more 14 Debian Linux, Fedora, Linux Kernel and 11 more 2026-10-14 N/A 4.4 MEDIUM
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
CVE-2023-1206 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-10-14 N/A 5.7 MEDIUM
A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%.
CVE-2023-0361 5 Debian, Fedoraproject, Gnu and 2 more 7 Debian Linux, Fedora, Gnutls and 4 more 2026-10-14 N/A 7.4 HIGH
A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
CVE-2022-48303 2 Fedoraproject, Gnu 2 Fedora, Tar 2026-10-14 N/A 5.5 MEDIUM
GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.
CVE-2022-45873 2 Fedoraproject, Systemd Project 2 Fedora, Systemd 2026-10-14 N/A 5.5 MEDIUM
systemd 250 and 251 allows local users to achieve a systemd-coredump deadlock by triggering a crash that has a long backtrace. This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology is to crash a binary calling the same function recursively, and put it in a deeply nested directory to make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16 is set for the systemd/units/systemd-coredump.socket file.
CVE-2022-45061 3 Fedoraproject, Netapp, Python 10 Fedora, Active Iq Unified Manager, Bootstrap Os and 7 more 2026-10-14 N/A 7.5 HIGH
An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.
CVE-2022-43680 4 Debian, Fedoraproject, Libexpat Project and 1 more 18 Debian Linux, Fedora, Libexpat and 15 more 2026-10-14 N/A 7.5 HIGH
In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations.
CVE-2022-43551 4 Fedoraproject, Haxx, Netapp and 1 more 7 Fedora, Curl, Active Iq Unified Manager and 4 more 2026-10-14 N/A 7.5 HIGH
A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text transfer. Because it would store the info IDN encoded but look for it IDN decoded.
CVE-2022-42916 4 Apple, Fedoraproject, Haxx and 1 more 4 Macos, Fedora, Curl and 1 more 2026-10-14 N/A 7.5 HIGH
In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step) even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0 2021-05-26.
CVE-2022-42915 5 Apple, Fedoraproject, Haxx and 2 more 13 Macos, Fedora, Curl and 10 more 2026-10-14 N/A 8.1 HIGH
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0.
CVE-2022-42722 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 5.5 MEDIUM
In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices.
CVE-2022-42721 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 5.5 MEDIUM
A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in turn, potentially execute code.
CVE-2022-42720 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 7.8 HIGH
Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-free conditions to potentially execute code.
CVE-2022-42719 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 8.8 HIGH
A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.x before 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.
CVE-2022-41674 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 8.1 HIGH
An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c.
CVE-2022-40768 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-14 N/A 5.5 MEDIUM
drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
CVE-2022-40674 3 Debian, Fedoraproject, Libexpat Project 3 Debian Linux, Fedora, Libexpat 2026-10-14 N/A 8.1 HIGH
libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c.
CVE-2022-37454 8 Debian, Extended Keccak Code Package Project, Fedoraproject and 5 more 8 Debian Linux, Extended Keccak Code Package, Fedora and 5 more 2026-10-14 N/A 9.8 CRITICAL
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface.
CVE-2022-37434 6 Apple, Debian, Fedoraproject and 3 more 21 Ipados, Iphone Os, Macos and 18 more 2026-10-14 N/A 9.8 CRITICAL
zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).
CVE-2026-90995 2 Fedoraproject, Redhat 3 Sssd, Enterprise Linux, Openshift Container Platform 2026-10-14 N/A 5.5 MEDIUM
A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the `pam_app_services` configuration is enabled and the service item is omitted from the request, a NULL pointer dereference can occur. This vulnerability leads to a denial of service, causing the PAM responder to crash and disrupt authentication services.
