| CVE-2021-47383 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Eus | 2025-12-10 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: tty: Fix out-of-bound vmalloc access in imageblit This issue happens when a userspace program does an ioctl FBIOPUT_VSCREENINFO passing the fb_var_screeninfo struct containing only the fields xres, yres, and bits_per_pixel with values. If this struct is the same as the previous ioctl, the vc_resize() detects it and doesn't call the resize_screen(), leaving the fb_var_screeninfo incomplete. And this leads to the updatescrollmode() calculates a wrong value to fbcon_display->vrows, which makes the real_y() return a wrong value of y, and that value, eventually, causes the imageblit to access an out-of-bound address value. To solve this issue I made the resize_screen() be called even if the screen does not need any resizing, so it will "fix and fill" the fb_var_screeninfo independently. | ||||
| CVE-2021-47548 | 2 Linux, Redhat | 6 Linux Kernel, Enterprise Linux, Rhel Aus and 3 more | 2025-12-10 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off; because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function returns. | ||||

| CVE-2021-47356 | 2 Linux, Redhat | 6 Linux Kernel, Enterprise Linux, Rhel Aus and 3 more | 2025-12-10 | 7.7 High |
| In the Linux kernel, the following vulnerability has been resolved: mISDN: fix possible use-after-free in HFC_cleanup() This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself. | ||||
| CVE-2021-47352 | 2 Linux, Redhat | 6 Linux Kernel, Enterprise Linux, Rhel Aus and 3 more | 2025-12-10 | 7.8 High |

| 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-2025-5318 | 2 Libssh, Redhat | 10 Libssh, Enterprise Linux, Openshift and 7 more | 2025-12-05 | 5.4 Medium |
| A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior. | ||||
| CVE-2025-62231 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-04 | 7.3 High |
| A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash. | ||||
| CVE-2025-62230 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-04 | 7.3 High |
| A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect. | ||||
| CVE-2025-62229 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2025-12-04 | 7.3 High |
| A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute arbitrary code or cause a denial of service. | ||||
