| CVE-2021-47185 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-12-10 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: tty: tty_buffer: Fix the softlockup issue in flush_to_ldisc When running ltp testcase(ltp/testcases/kernel/pty/pty04.c) with arm64, there is a soft lockup, which look like this one: Workqueue: events_unbound flush_to_ldisc Call trace: dump_backtrace+0x0/0x1ec show_stack+0x24/0x30 dump_stack+0xd0/0x128 panic+0x15c/0x374 watchdog_timer_fn+0x2b8/0x304 __run_hrtimer+0x88/0x2c0 __hrtimer_run_queues+0xa4/0x120 hrtimer_interrupt+0xfc/0x270 arch_timer_handler_phys+0x40/0x50 handle_percpu_devid_irq+0x94/0x220 __handle_domain_irq+0x88/0xf0 gic_handle_irq+0x84/0xfc el1_irq+0xc8/0x180 slip_unesc+0x80/0x214 [slip] tty_ldisc_receive_buf+0x64/0x80 tty_port_default_receive_buf+0x50/0x90 flush_to_ldisc+0xbc/0x110 process_one_work+0x1d4/0x4b0 worker_thread+0x180/0x430 kthread+0x11c/0x120 In the testcase pty04, The first process call the write syscall to send data to the pty master. At the same time, the workqueue will do the flush_to_ldisc to pop data in a loop until there is no more data left. When the sender and workqueue running in different core, the sender sends data fastly in full time which will result in workqueue doing work in loop for a long time and occuring softlockup in flush_to_ldisc with kernel configured without preempt. So I add need_resched check and cond_resched in the flush_to_ldisc loop to avoid it. | ||||
| CVE-2024-12087 | 8 Almalinux, Archlinux, Gentoo and 5 more | 20 Almalinux, Arch Linux, Linux and 17 more | 2025-12-10 | 6.5 Medium |
| A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client. | ||||

| CVE-2025-49178 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-09 | 5.5 Medium |
| A flaw was found in the X server's request handling. Non-zero 'bytes to ignore' in a client's request can cause the server to skip processing another client's request, potentially leading to a denial of service. | ||||
| CVE-2025-49180 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-09 | 7.8 High |
| A flaw was found in the RandR extension, where the RRChangeProviderProperty function does not properly validate input. This issue leads to an integer overflow when computing the total size to allocate. | ||||
| CVE-2025-49179 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-09 | 7.3 High |
| A flaw was found in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks. | ||||
| CVE-2025-49177 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2025-12-09 | 6.1 Medium |
| A flaw was found in the XFIXES extension. The XFixesSetClientDisconnectMode handler does not validate the request length, allowing a client to read unintended memory from previous requests. | ||||
| CVE-2025-59089 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2025-12-09 | 5.9 Medium |
| If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients. | ||||
| CVE-2025-59088 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2025-12-09 | 8.6 High |
| If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected. | ||||
| CVE-2025-49176 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-09 | 7.3 High |
| A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check. | ||||
| CVE-2024-8176 | 1 Redhat | 10 Devworkspace, Discovery, Enterprise Linux and 7 more | 2025-12-09 | 7.5 High |
| A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage. | ||||
| CVE-2025-14104 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-12-09 | 6.1 Medium |
| A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils utilities writing to the password database. | ||||
| CVE-2025-4598 | 5 Debian, Linux, Oracle and 2 more | 8 Debian Linux, Linux Kernel, Linux and 5 more | 2025-12-08 | 4.7 Medium |
| A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process. A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality. | ||||
| CVE-2025-66287 | 1 Redhat | 1 Enterprise Linux | 2025-12-08 | 8.8 High |
| A flaw was found in WebKitGTK. Processing malicious web content can cause an unexpected process crash due to improper memory handling. | ||||
| CVE-2025-9784 | 1 Redhat | 15 Apache Camel Hawtio, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 12 more | 2025-12-08 | 7.5 High |
| A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS). | ||||
| CVE-2025-13947 | 1 Redhat | 1 Enterprise Linux | 2025-12-08 | 7.4 High |
| A flaw was found in WebKitGTK. This vulnerability allows remote, user-assisted information disclosure that can reveal any file the user is permitted to read via abusing the file drag-and-drop mechanism where WebKitGTK does not verify that drag operations originate from outside the browser. | ||||
| CVE-2025-13502 | 1 Redhat | 1 Enterprise Linux | 2025-12-08 | 7.5 High |
| A flaw was found in WebKitGTK and WPE WebKit. This vulnerability allows an out-of-bounds read and integer underflow, leading to a UIProcess crash (DoS) via a crafted payload to the GLib remote inspector server. | ||||
| CVE-2025-21887 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-12-06 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ovl: fix UAF in ovl_dentry_update_reval by moving dput() in ovl_link_up The issue was caused by dput(upper) being called before ovl_dentry_update_reval(), while upper->d_flags was still accessed in ovl_dentry_remote(). Move dput(upper) after its last use to prevent use-after-free.
