| CVE-2026-1979 | 1 Mruby | 1 Mruby | 2026-04-18 | 5.3 Medium |
| A flaw has been found in mruby up to 3.4.0. This affects the function mrb_vm_exec of the file src/vm.c of the component JMPNOT-to-JMPIF Optimization. Executing a manipulation can lead to use after free. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called e50f15c1c6e131fa7934355eb02b8173b13df415. It is advisable to implement a patch to correct this issue. | ||||
| CVE-2026-24917 | 1 Huawei | 2 Emui, Harmonyos | 2026-04-18 | 6.5 Medium |
| UAF vulnerability in the security module. Impact: Successful exploitation of this vulnerability may affect availability. | ||||
| CVE-2026-24491 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, video_timer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-24681 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, aAsynchronous bulk transfer completions can use a freed channel callback after URBDRC channel close, leading to a use after free in urb_write_completion. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-21326 | 3 Adobe, Apple, Microsoft | 3 After Effects, Macos, Windows | 2026-04-18 | 7.8 High |
| After Effects versions 25.6 and earlier are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | ||||
| CVE-2026-2441 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-04-18 | 8.8 High |
| Use after free in CSS in Google Chrome prior to 145.0.7632.75 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2026-23216 | 1 Linux | 1 Linux Kernel | 2026-04-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count() In iscsit_dec_conn_usage_count(), the function calls complete() while holding the conn->conn_usage_lock. As soon as complete() is invoked, the waiter (such as iscsit_close_connection()) may wake up and proceed to free the iscsit_conn structure. If the waiter frees the memory before the current thread reaches spin_unlock_bh(), it results in a KASAN slab-use-after-free as the function attempts to release a lock within the already-freed connection structure. Fix this by releasing the spinlock before calling complete(). | ||||
| CVE-2026-2656 | 1 Chaiscript | 1 Chaiscript | 2026-04-18 | 2.5 Low |
| A flaw has been found in ChaiScript up to 6.1.0. This affects the function chaiscript::Type_Info::bare_equal of the file include/chaiscript/dispatchkit/type_info.hpp. This manipulation causes use after free. The attack requires local access. The attack's complexity is rated as high. The exploitability is reported as difficult. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet. | ||||
| CVE-2026-2408 | 1 Tanium | 2 Cloud Workloads, Service Cloudworkloads | 2026-04-18 | 4.7 Medium |
| Tanium addressed a use-after-free vulnerability in the Cloud Workloads Enforce client extension. | ||||
| CVE-2026-2889 | 1 Ccextractor | 1 Ccextractor | 2026-04-18 | 3.3 Low |
| A vulnerability was detected in CCExtractor up to 0.96.5. Affected is the function processmp4 in the library src/lib_ccx/mp4.c. Performing a manipulation results in use after free. The attack is only possible with local access. The exploit is now public and may be used. Upgrading to version 0.96.6 is able to address this issue. The patch is named fd7271bae238ccb3ae8a71304ea64f0886324925. You should upgrade the affected component. | ||||
| CVE-2026-25952 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 9.8 Critical |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_SetWindowMinMaxInfo` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` in `xf_rail_server_min_max_info` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue. | ||||
| CVE-2026-25954 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_local_move_size` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue. | ||||
| CVE-2026-0027 | 1 Google | 1 Android | 2026-04-18 | 6.7 Medium |
| In smmu_detach_dev of arm-smmu-v3.c, there is a possible out of bounds write due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. | ||||
| CVE-2026-28688 | 1 Imagemagick | 1 Imagemagick | 2026-04-18 | 4 Medium |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. | ||||
| CVE-2026-23270 | 1 Linux | 1 Linux Kernel | 2026-04-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: Only allow act_ct to bind to clsact/ingress qdiscs and shared blocks As Paolo said earlier [1]: "Since the blamed commit below, classify can return TC_ACT_CONSUMED while the current skb being held by the defragmentation engine. As reported by GangMin Kim, if such packet is that may cause a UaF when the defrag engine later on tries to tuch again such packet." act_ct was never meant to be used in the egress path, however some users are attaching it to egress today [2]. Attempting to reach a middle ground, we noticed that, while most qdiscs are not handling TC_ACT_CONSUMED, clsact/ingress qdiscs are. With that in mind, we address the issue by only allowing act_ct to bind to clsact/ingress qdiscs and shared blocks. That way it's still possible to attach act_ct to egress (albeit only with clsact).

| CVE-2026-23245 | 1 Linux | 1 Linux Kernel | 2026-04-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: act_gate: snapshot parameters with RCU on replace The gate action can be replaced while the hrtimer callback or dump path is walking the schedule list. Convert the parameters to an RCU-protected snapshot and swap updates under tcf_lock, freeing the previous snapshot via call_rcu(). When REPLACE omits the entry list, preserve the existing schedule so the effective state is unchanged. | ||||
| CVE-2026-23227 | 1 Linux | 1 Linux Kernel | 2026-04-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: use ctx->lock to protect struct vidi_context member variables related to memory alloc/free Exynos Virtual Display driver performs memory alloc/free operations without lock protection, which easily causes concurrency problem. For example, use-after-free can occur in race scenario like this: ``` CPU0 CPU1 CPU2 ---- ---- ---- vidi_connection_ioctl() if (vidi->connection) // true drm_edid = drm_edid_alloc(); // alloc drm_edid ... ctx->raw_edid = drm_edid; ... drm_mode_getconnector() drm_helper_probe_single_connector_modes() vidi_get_modes() if (ctx->raw_edid) // true drm_edid_dup(ctx->raw_edid); if (!drm_edid) // false ... vidi_connection_ioctl() if (vidi->connection) // false drm_edid_free(ctx->raw_edid); // free drm_edid ... drm_edid_alloc(drm_edid->edid) kmemdup(edid); // UAF!! ... ``` To prevent these vulns, at least in vidi_context, member variables related to memory alloc/free should be protected with ctx->lock. | ||||
