CVE-2026-41484 1 Opentelemetry 2 Opentelemetry-dotnet-contrib, Opentelemetry.exporter.onecollector 2026-05-15 5.3 Medium
OpenTelemetry.Exporter.OneCollector is a .NET exporter that sends telemetry to a OneCollector back-end over HTTP. In versions 1.15.0 and earlier, when a request to the configured back-end or collector results in an unsuccessful HTTP 4xx or 5xx response, the HttpJsonPostTransport class reads the entire response body into memory with no upper bound on the number of bytes consumed in order to include the error response in operator logs. An attacker who controls the configured endpoint, or who can intercept traffic to it via a man-in-the-middle attack, can return an arbitrarily large response body. This causes unbounded heap allocation in the consuming process, leading to high transient memory pressure, garbage-collection stalls, or an OutOfMemoryException that terminates the process. As a workaround, use network-level controls such as firewall rules, mTLS, or a service mesh to prevent man-in-the-middle attacks on the configured back-end or collector endpoint. This issue is fixed in version 1.15.1, which limits the number of bytes read from the response body in an error condition to 4 MiB.
CVE-2026-43286 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: restore failed global reservations to subpool Commit a833a693a490 ("mm: hugetlb: fix incorrect fallback for subpool") fixed an underflow error for hstate->resv_huge_pages caused by incorrectly attributing globally requested pages to the subpool's reservation. Unfortunately, this fix also introduced the opposite problem, which would leave spool->used_hpages elevated if the globally requested pages could not be acquired. This is because while a subpool's reserve pages only accounts for what is requested and allocated from the subpool, its "used" counter keeps track of what is consumed in total, both from the subpool and globally. Thus, we need to adjust spool->used_hpages in the other direction, and make sure that globally requested pages are uncharged from the subpool's used counter. Each failed allocation attempt increments the used_hpages counter by how many pages were requested from the global pool. Ultimately, this renders the subpool unusable, as used_hpages approaches the max limit. The issue can be reproduced as follows: 1. Allocate 4 hugetlb pages 2. Create a hugetlb mount with max=4, min=2 3. Consume 2 pages globally 4. Request 3 pages from the subpool (2 from subpool + 1 from global) 4.1 hugepage_subpool_get_pages(spool, 3) succeeds. used_hpages += 3 4.2 hugetlb_acct_memory(h, 1) fails: no global pages left used_hpages -= 2 5. Subpool now has used_hpages = 1, despite not being able to successfully allocate any hugepages. It believes it can now only allocate 3 more hugepages, not 4. With each failed allocation attempt incrementing the used counter, the subpool eventually reaches a point where its used counter equals its max counter. At that point, any future allocations that try to allocate hugeTLB pages from the subpool will fail, despite the subpool not having any of its hugeTLB pages consumed by any user. Once this happens, there is no way to make the subpool usable again, since there is no way to decrement the used counter as no process is really consuming the hugeTLB pages. The underflow issue that the original commit fixes still remains fixed as well. Without this fix, used_hpages would keep on leaking if hugetlb_acct_memory() fails.
CVE-2026-43372 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: dsa: microchip: Fix error path in PTP IRQ setup If request_threaded_irq() fails during the PTP message IRQ setup, the newly created IRQ mapping is never disposed. Indeed, the ksz_ptp_irq_setup()'s error path only frees the mappings that were successfully set up. Dispose the newly created mapping if the associated request_threaded_irq() fails at setup.
CVE-2026-44544 1 Gittuf 1 Gittuf 2026-05-15 N/A
gittuf is a platform-agnostic Git security system. Prior to 0.14.0, an attacker with push access to gittuf's Reference State Log (RSL) can roll back the current policy to any previous policy trusted by the current set of root keys. gittuf determines the policy to load by inspecting the RSL. Except for the very first policy (which is automatically trusted given gittuf's TOFU model, or verified against manually specified keys), whenever an RSL entry that points to a new policy is encountered, gittuf validates that this policy is trusted. This is done by checking that the new policy’s root metadata is signed by the required threshold of the current policy's root keys. Because of this, an attacker with push access to the RSL may create a new entry that references an old policy (that is trusted by the most recent policy's set of root keys), thereby rolling back gittuf's policy to the attacker's chosen state. This vulnerability is fixed in 0.14.0.
CVE-2026-44448 1 Frappe 1 Erpnext 2026-05-15 5.9 Medium
ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.102.0 and 16.11.0, certain endpoints failed to enforce proper authorization checks, allowing users to modify data beyond their permitted role. This vulnerability is fixed in 15.102.0 and 16.11.0.
CVE-2026-45158 1 Opnsense 2 Core, Opnsense 2026-05-15 9.1 Critical
OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.8, unsanitized user input is passed to the DHCP configuration of the configured interface, which is processed by a shell script, allowing remote code execution as root on the underlying operating system. This vulnerability is fixed in 26.1.8.
CVE-2026-43364 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ublk: fix NULL pointer dereference in ublk_ctrl_set_size() ublk_ctrl_set_size() unconditionally dereferences ub->ub_disk via set_capacity_and_notify() without checking if it is NULL. ub->ub_disk is NULL before UBLK_CMD_START_DEV completes (it is only assigned in ublk_ctrl_start_dev()) and after UBLK_CMD_STOP_DEV runs (ublk_detach_disk() sets it to NULL). Since the UBLK_CMD_UPDATE_SIZE handler performs no state validation, a user can trigger a NULL pointer dereference by sending UPDATE_SIZE to a device that has been added but not yet started, or one that has been stopped. Fix this by checking ub->ub_disk under ub->mutex before dereferencing it, and returning -ENODEV if the disk is not available.
CVE-2026-43363 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: x86/apic: Disable x2apic on resume if the kernel expects so When resuming from s2ram, firmware may re-enable x2apic mode, which may have been disabled by the kernel during boot either because it doesn't support IRQ remapping or for other reasons. This causes the kernel to continue using the xapic interface, while the hardware is in x2apic mode, which causes hangs. This happens on defconfig + bare metal + s2ram. Fix this in lapic_resume() by disabling x2apic if the kernel expects it to be disabled, i.e. when x2apic_mode = 0. The ACPI v6.6 spec, Section 16.3 [1] says firmware restores either the pre-sleep configuration or initial boot configuration for each CPU, including MSR state: When executing from the power-on reset vector as a result of waking from an S2 or S3 sleep state, the platform firmware performs only the hardware initialization required to restore the system to either the state the platform was in prior to the initial operating system boot, or to the pre-sleep configuration state. In multiprocessor systems, non-boot processors should be placed in the same state as prior to the initial operating system boot. (further ahead) If this is an S2 or S3 wake, then the platform runtime firmware restores minimum context of the system before jumping to the waking vector. This includes: CPU configuration. Platform runtime firmware restores the pre-sleep configuration or initial boot configuration of each CPU (MSR, MTRR, firmware update, SMBase, and so on). Interrupts must be disabled (for IA-32 processors, disabled by CLI instruction). (and other things) So at least as per the spec, re-enablement of x2apic by the firmware is allowed if "x2apic on" is a part of the initial boot configuration.

CVE-2025-66660 1 Amd 12 Instinct Mi210, Instinct Mi250, Instinct Mi300a and 9 more 2026-05-15 N/A
Insufficient parameter sanitization in TEE SOC Driver could allow an attacker to issue a malformed DRV_SOC_CMD_ID_SRIOV_CHECK_TA_COMPAT to cause incorrect shared memory mapping, potentially resulting in unexpected behavior.
CVE-2026-44195 1 Opnsense 2 Core, Opnsense 2026-05-15 5.3 Medium
OPNsense is a FreeBSD based firewall and routing platform. Prior to 26.1.7, a logic flaw in the OPNsense lockout_handler allows an unauthenticated attacker to continuously reset the authentication failure counter for their IP address. By interjecting a crafted username containing a success keyword ("Accepted" or "Successful login") between normal brute-force attempts, an attacker can prevent the failure counter from ever reaching the lockout threshold. This vulnerability is fixed in 26.1.7.
CVE-2026-43358 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: btrfs: add missing RCU unlock in error path in try_release_subpage_extent_buffer() Call rcu_read_lock() before exiting the loop in try_release_subpage_extent_buffer() because there is a rcu_read_unlock() call past the loop. This has been detected by the Clang thread-safety analyzer.
CVE-2026-43357 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iio: gyro: mpu3050-core: fix pm_runtime error handling The return value of pm_runtime_get_sync() is not checked, allowing the driver to access hardware that may fail to resume. The device usage count is also unconditionally incremented. Use pm_runtime_resume_and_get() which propagates errors and avoids incrementing the usage count on failure. In preenable, add pm_runtime_put_autosuspend() on set_8khz_samplerate() failure since postdisable does not run when preenable fails.
CVE-2026-43356 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iio: imu: adis: Fix NULL pointer dereference in adis_init The adis_init() function dereferences adis->ops to check if the individual function pointers (write, read, reset) are NULL, but does not first check if adis->ops itself is NULL. Drivers like adis16480, adis16490, adis16545 and others do not set custom ops and rely on adis_init() assigning the defaults. Since struct adis is zero-initialized by devm_iio_device_alloc(), adis->ops is NULL when adis_init() is called, causing a NULL pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 pc : adis_init+0xc0/0x118 Call trace: adis_init+0xc0/0x118 adis16480_probe+0xe0/0x670 Fix this by checking if adis->ops is NULL before dereferencing it, falling through to assign the default ops in that case.

CVE-2026-42855 1 Espressif 1 Arduino-esp32 2026-05-15 7.5 High
arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, the WebServer Digest authentication implementation in arduino-esp32 computes the authentication hash using the URI field from the client's Authorization header, without verifying that it matches the actual requested URI. This allows an attacker who possesses any valid digest response (computed for URI-A) to authenticate requests to a completely different protected URI (URI-B), bypassing per-resource access control. This vulnerability is fixed in 3.3.8.

CVE-2026-44866 2 Arubanetworks, Hpe 3 Arubaos, Sd-wan, Arubaos 2026-05-15 7.2 High
Command injection vulnerabilities exist in the web-based management interface of AOS-8 and AOS-10 Operating Systems. Successful exploitation of these vulnerabilities could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system.
CVE-2026-44572 1 Vercel 1 Next.js 2026-05-15 3.7 Low
Next.js is a React framework for building full-stack web applications. From 12.2.0 to before 15.5.16 and 16.2.5, an external client could send a x-nextjs-data header on a normal request to a path handled by middleware that returns a redirect. When that happened, the middleware/proxy could treat the request as a data request and replace the standard Location redirect header with the internal x-nextjs-redirect header. Browsers do not follow x-nextjs-redirect, so the response became an unusable redirect for normal clients. If the application was deployed behind a CDN or reverse proxy that caches 3xx responses without varying on this header, a single attacker request could poison the cached redirect response for the affected path. Subsequent visitors could then receive a cached redirect response without a Location header, causing a denial of service for that redirect path until the cache entry expired or was purged. This vulnerability is fixed in 15.5.16 and 16.2.5.
CVE-2026-43367 1 Linux 1 Linux Kernel 2026-05-15 5.5 Medium
