CVE-2023-6683 2 Qemu, Redhat 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more 2026-11-05 6.5 Medium
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.

CVE-2026-48174 2026-11-05 N/A
In the NR RRC component, improper handling of messages before authentication triggers a data abort, which leads to a denial‑of‑service condition.
CVE-2026-69025 2026-11-05 N/A
In the Exynos NPU driver, improper validation of user input in the ioctl handler can lead to an out-of-bounds write, which causes a denial of service
CVE-2026-120046 1 Nezhahq 1 Nezha 2026-11-05 5.3 Medium
Nezha 2.0.0 before 2.4.0 contains a NULL pointer dereference vulnerability in ServiceSentinel.loadTodayStats that allows authenticated users to crash the dashboard by deleting a service. Attackers can delete their own service via POST /api/v1/batch-delete/service, leaving orphaned service_histories rows that crash the non-TSDB dashboard on its next startup until removed manually.
CVE-2026-119760 1 Sniproxy Project 1 Sniproxy 2026-11-05 7.5 High
sniproxy through 0.7.0 contains a NULL pointer dereference vulnerability in resolv_cancel() that allows remote unauthenticated attackers to crash the daemon by sending overlong hostnames. Attackers can send a 254 or 255 character TLS SNI name or HTTP Host header matching a wildcard backend, then close the connection to terminate the proxy.
CVE-2026-18453 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-11-04 7.5 High
A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.
CVE-2026-1584 2 Gnu, Redhat 6 Gnutls, Enterprise Linux, Hardened Images and 3 more 2026-11-04 7.5 High
A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition.
CVE-2025-32913 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-11-04 7.5 High

CVE-2026-99225 1 Linux 2 Linux, Linux Kernel 2026-11-04 4.7 Medium
In the Linux kernel, the following vulnerability has been resolved: keys: Check the authorization payload in process keyring searches An authorization payload and its saved credentials must remain valid while search_process_keyrings_rcu() searches the requestor's keyrings. The function validates the authorization key, then separately loads payload.data[0] and unconditionally reads rka->cred. Validation does not prevent request_key_auth_revoke() from clearing the payload. A request-key helper can assume authority and fork a descendant that inherits the authorization key. If the descendant misses in its own keyrings, it falls back to the saved requestor credentials. Successful target instantiation invalidates the authorization key without clearing the payload. After the helper exits, UMH_WAIT_PROC returns to the requester, which calls complete_request_key() and revokes that key. With the descendant paused after validation, the paths can interleave as follows: 1. The descendant enters search_process_keyrings_rcu() under RCU and key_validate() succeeds. 2. The helper instantiates the target, invalidates the authorization key, and exits. 3. The requester resumes from UMH_WAIT_PROC, calls complete_request_key(), and revokes the authorization key. request_key_auth_revoke() sets its payload pointer to NULL. 4. The descendant loads NULL and dereferences rka->cred. This NULL dereference can oops the kernel. RCU delays payload disposal but does not prevent the pointer from being cleared. Load the payload with dereference_key_rcu() and require a non-NULL result before validating the authorization key and searching its saved credentials. A non-NULL payload and its credentials remain alive for the caller's RCU read-side section; a cleared payload skips the fallback search and follows the existing error selection. KASAN report as below: Oops: general protection fault, probably for non-canonical address 0xdffffc0000000005: 0000 [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f] RIP: 0010:search_process_keyrings_rcu+0x32b/0x790
