| CVE-2025-41118 | 1 Grafana | 1 Pyroscope | 2026-04-24 | 9.1 Critical |
| Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS). If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API. To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems. This vulnerability is fixed in versions: 1.15.x: 1.15.2 and above. 1.16.x: 1.16.1 and above. 1.17.x: 1.17.0 and above (i.e. all versions). Thanks to Théo Cusnir for reporting this vulnerability to us via our bug bounty program. | ||||

| Stack traces in Grafana's Explore Traces view can be rendered as raw HTML, and thus inject malicious JavaScript in the browser. This would require malicious JavaScript to be entered into the stack trace field. Only datasources with the Jaeger HTTP API appear to be affected; Jaeger gRPC and Tempo do not appear affected whatsoever. | ||||

| CVE-2026-21722 | 1 Grafana | 2 Grafana, Grafana Enterprise | 2026-04-24 | 5.3 Medium |
| Public dashboards with annotations enabled did not limit their annotation timerange to the locked timerange of the public dashboard. This means one could read the entire history of annotations visible on the specific dashboard, even those outside the locked timerange. This did not leak any annotations that would not otherwise be visible on the public dashboard. | ||||

| CVE-2026-4922 | 1 Gitlab | 1 Gitlab | 2026-04-24 | 8.1 High |
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.0 before 18.9.6, 18.10 before 18.10.4, and 18.11 before 18.11.1 that could have allowed an unauthenticated user to execute GraphQL mutations on behalf of authenticated users due to insufficient CSRF protection. | ||||
| CVE-2026-23337 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pinctrl: pinconf-generic: Fix memory leak in pinconf_generic_parse_dt_config() In pinconf_generic_parse_dt_config(), if parse_dt_cfg() fails, it returns directly. This bypasses the cleanup logic and results in a memory leak of the cfg buffer. Fix this by jumping to the out label on failure, ensuring kfree(cfg) is called before returning. | ||||
| CVE-2026-23342 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix race in cpumap on PREEMPT_RT On PREEMPT_RT kernels, the per-CPU xdp_bulk_queue (bq) can be accessed concurrently by multiple preemptible tasks on the same CPU. The original code assumes bq_enqueue() and __cpu_map_flush() run atomically with respect to each other on the same CPU, relying on local_bh_disable() to prevent preemption. However, on PREEMPT_RT, local_bh_disable() only calls migrate_disable() (when PREEMPT_RT_NEEDS_BH_LOCK is not set) and does not disable preemption, which allows CFS scheduling to preempt a task during bq_flush_to_queue(), enabling another task on the same CPU to enter bq_enqueue() and operate on the same per-CPU bq concurrently. This leads to several races: 1. Double __list_del_clearprev(): after bq->count is reset in bq_flush_to_queue(), a preempting task can call bq_enqueue() -> bq_flush_to_queue() on the same bq when bq->count reaches CPU_MAP_BULK_SIZE. Both tasks then call __list_del_clearprev() on the same bq->flush_node, the second call dereferences the prev pointer that was already set to NULL by the first. 2. bq->count and bq->q[] races: concurrent bq_enqueue() can corrupt the packet queue while bq_flush_to_queue() is processing it. The race between task A (__cpu_map_flush -> bq_flush_to_queue) and task B (bq_enqueue -> bq_flush_to_queue) on the same CPU: Task A (xdp_do_flush) Task B (cpu_map_enqueue) ---------------------- ------------------------ bq_flush_to_queue(bq) spin_lock(&q->producer_lock) /* flush bq->q[] to ptr_ring */ bq->count = 0 spin_unlock(&q->producer_lock) bq_enqueue(rcpu, xdpf) <-- CFS preempts Task A --> bq->q[bq->count++] = xdpf /* ... more enqueues until full ... */ bq_flush_to_queue(bq) spin_lock(&q->producer_lock) /* flush to ptr_ring */ spin_unlock(&q->producer_lock) __list_del_clearprev(flush_node) /* sets flush_node.prev = NULL */ <-- Task A resumes --> __list_del_clearprev(flush_node) flush_node.prev->next = ... /* prev is NULL -> kernel oops */ Fix this by adding a local_lock_t to xdp_bulk_queue and acquiring it in bq_enqueue() and __cpu_map_flush(). These paths already run under local_bh_disable(), so use local_lock_nested_bh() which on non-RT is a pure annotation with no overhead, and on PREEMPT_RT provides a per-CPU sleeping lock that serializes access to the bq. To reproduce, insert an mdelay(100) between bq->count = 0 and __list_del_clearprev() in bq_flush_to_queue(), then run reproducer provided by syzkaller. | ||||
| CVE-2026-33797 | 2 Juniper, Juniper Networks | 4 Junos, Junos Os Evolved, Junos Os and 1 more | 2026-04-23 | 7.4 High |
| An Improper Input Validation vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker, sending a specific genuine BGP packet in an already established BGP session to reset only that session causing a Denial of Service (DoS). An attacker repeatedly sending the packet will sustain the Denial of Service (DoS).This issue affects Junos OS: * 25.2 versions before 25.2R2 This issue does not affect Junos OS versions before 25.2R1. This issue affects Junos OS Evolved: * 25.2-EVO versions before 25.2R2-EVO This issue does not affect Junos OS Evolved versions before 25.2R1-EVO. eBGP and iBGP are affected. IPv4 and IPv6 are affected. | ||||
| CVE-2026-23331 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: udp: Unhash auto-bound connected sk from 4-tuple hash table when disconnected. Let's say we bind() an UDP socket to the wildcard address with a non-zero port, connect() it to an address, and disconnect it from the address. bind() sets SOCK_BINDPORT_LOCK on sk->sk_userlocks (but not SOCK_BINDADDR_LOCK), and connect() calls udp_lib_hash4() to put the socket into the 4-tuple hash table. Then, __udp_disconnect() calls sk->sk_prot->rehash(sk). It computes a new hash based on the wildcard address and moves the socket to a new slot in the 4-tuple hash table, leaving a garbage in the chain that no packet hits. Let's remove such a socket from 4-tuple hash table when disconnected. Note that udp_sk(sk)->udp_portaddr_hash needs to be udpated after udp_hash4_dec(hslot2) in udp_unhash4(). | ||||
