| CVE-2026-19445 | 2 Python, Redhat | 2 Cpython, Hummingbird | 2026-10-03 | 8.1 High |
| A remote, unauthenticated TLS client can make a server crash or call through a freed pointer if its sni_callback assigns a different context to SSLSocket.context (the documented way to select a certificate per server name) and nothing else keeps the original ssl.SSLContext alive. Typical cases are servers that create an SSLContext per connection or replace it while connections are open; servers that wrap their listening socket with it are not affected. Mitigation: keep a reference to every SSLContext that sets sni_callback for the lifetime of the server. TLS clients are not affected. | ||||
| CVE-2026-64008 | 1 Linux | 1 Linux Kernel | 2026-10-02 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: accel/rocket: fix UAF via dangling GEM handle in create_bo rocket_ioctl_create_bo() inserts a GEM handle into the file's IDR via drm_gem_handle_create() early on, then performs several operations that can fail (sgt allocation, drm_mm insert, iommu_map). If any fail after the handle is live, the error path calls drm_gem_shmem_object_free() which kfree's the object without removing the handle from the IDR. This leaves a dangling handle pointing to freed slab memory. Any subsequent ioctl using that handle (PREP_BO, FINI_BO, SUBMIT) calls drm_gem_object_lookup() and dereferences freed memory (UAF). Fix by moving drm_gem_handle_create() to after all fallible operations succeed, matching the pattern used by panfrost, lima, and etnaviv. Also fix drm_mm_insert_node_generic() whose return value was silently overwritten by iommu_map_sgtable() on the next line. Add the missing error check.

| CVE-2026-15442 | 1 Wolfssl | 1 Wolfssl | 2026-10-02 | 5.3 Medium |
| In all builds that make use of (D)TLS, including default builds, there is a series of conditional states during the TLS shutdown which could lead to a heap-use-after free. If an application ended up getting a partial wolfSSL_read() which is sometimes caused by a small user buffer passed in, then called wolfSSL_shutdown for a bidirectional close and attempted to wolfSSL_read() again while the peer continues trying to send data during the shutdown it would lead to a state where a potential heap-use-after free happened. | ||||
| CVE-2026-95372 | 1 Google | 1 Chrome | 2026-10-02 | 8.3 High |
| Use after free in Chromecast in Google Chrome prior to 154.0.8037.57 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2026-95373 | 1 Google | 1 Chrome | 2026-10-02 | 8.8 High |
| Use after free in DevTools in Google Chrome prior to 154.0.8037.57 allowed a remote attacker leveraging social engineering to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2026-76875 | 1 Pypy | 1 Pypy | 2026-10-02 | 5.3 Medium |
| PyPy before versions 3.11.16 and 3.12.14 contains a use-after-free vulnerability in the pyexpat module's ExternalEntityParserCreate function that allows attackers to corrupt memory by supplying a crafted XML document to applications that create external-entity sub-parsers without retaining a reference to the parent parser. The child parser retains a raw C back-pointer to the parent parser struct while PyPy's tracing garbage collector can free the parent's C struct, causing bundled libexpat to dereference the freed pointer on every parsed token, producing memory corruption. | ||||
| CVE-2026-74222 | 2 Denx, U-boot | 2 U-boot, U-boot | 2026-10-02 | 8.2 High |
| U-Boot before 2026.10-rc5 contains a use-after-free vulnerability in the httpc_recv_cb() function within the lwIP wget implementation. When HTTP data storage fails, the callback frees the connection PCB but returns ERR_BUF instead of ERR_ABRT, causing the TCP input path to access released memory and crash the bootloader. | ||||

| CVE-2018-15982 | 6 Adobe, Apple, Google and 3 more | 12 Flash Player, Flash Player Installer, Mac Os X and 9 more | 2026-10-01 | 7.8 High |
| Flash Player versions 31.0.0.153 and earlier, and 31.0.0.108 and earlier have a use after free vulnerability. Successful exploitation could lead to arbitrary code execution. | ||||
| CVE-2026-84895 | 1 Facebook | 1 Proxygen | 2026-10-01 | 7.3 High |
| In proxygen from v2026.04.06.00 until v2026.09.28.00, QuicWtSession::closeSession accesses its member fields after calling the base QuicWtSessionBase::closeSession method. The base method notifies the session handler, which may release the last reference to the session and destroy it. | ||||
| CVE-2026-58185 | 1 Apache | 1 Traffic Server | 2026-10-01 | 5.9 Medium |
| The Apache Traffic Server intercept plugin has a use-after-free. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue. | ||||
| CVE-2026-58164 | 1 Apache | 1 Traffic Server | 2026-10-01 | 7.5 High |
| Apache Traffic Server has use-after-free and time-of-check/time-of-use errors in remap configuration handling. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue. | ||||
| CVE-2026-101276 | 1 Es | 1 Iperf3 | 2026-10-01 | N/A |
| iperf3 3.21 (esnet/iperf) contains a remote, unauthenticated heap use-after-free: the server's per-test watchdog server_timer_proc() frees streams without cancelling/joining their worker threads, so a blocked worker dereferences a freed iperf_stream; fixed in 3.22. | ||||
| CVE-2026-57842 | 1 Netbsd | 1 Netbsd | 2026-10-01 | 7 High |
| NetBSD contains a use-after-free and double-free vulnerability in msg_recv_copyin() within the COMPAT_NETBSD32 compatibility layer due to a missing return statement before the cleanup label on the success path. Any local user able to execute a 32-bit binary on a 64-bit NetBSD system can trigger a kernel panic or memory corruption by calling recvmsg() with msg_iovlen between 9 and IOV_MAX, causing the kernel to access a freed iovec buffer and subsequently free the same allocation a second time. | ||||
