CVE-2026-23343 1 Linux 1 Linux Kernel 2026-04-23 7.8 High
In the Linux kernel, the following vulnerability has been resolved: xdp: produce a warning when calculated tailroom is negative Many ethernet drivers report xdp Rx queue frag size as being the same as DMA write size. However, the only user of this field, namely bpf_xdp_frags_increase_tail(), clearly expects a truesize. Such difference leads to unspecific memory corruption issues under certain circumstances, e.g. in ixgbevf maximum DMA write size is 3 KB, so when running xskxceiver's XDP_ADJUST_TAIL_GROW_MULTI_BUFF, 6K packet fully uses all DMA-writable space in 2 buffers. This would be fine, if only rxq->frag_size was properly set to 4K, but value of 3K results in a negative tailroom, because there is a non-zero page offset. We are supposed to return -EINVAL and be done with it in such case, but due to tailroom being stored as an unsigned int, it is reported to be somewhere near UINT_MAX, resulting in a tail being grown, even if the requested offset is too much (it is around 2K in the abovementioned test). This later leads to all kinds of unspecific calltraces.

CVE-2026-23326 1 Linux 1 Linux Kernel 2026-04-23 7.8 High
In the Linux kernel, the following vulnerability has been resolved: xsk: Fix fragment node deletion to prevent buffer leak After commit b692bf9a7543 ("xsk: Get rid of xdp_buff_xsk::xskb_list_node"), the list_node field is reused for both the xskb pool list and the buffer free list, this causes a buffer leak as described below. xp_free() checks if a buffer is already on the free list using list_empty(&xskb->list_node). When list_del() is used to remove a node from the xskb pool list, it doesn't reinitialize the node pointers. This means list_empty() will return false even after the node has been removed, causing xp_free() to incorrectly skip adding the buffer to the free list. Fix this by using list_del_init() instead of list_del() in all fragment handling paths, this ensures the list node is reinitialized after removal, allowing the list_empty() to work correctly.
CVE-2026-23315 1 Linux 1 Linux Kernel 2026-04-23 7.1 High
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: Fix possible oob access in mt76_connac2_mac_write_txwi_80211() Check frame length before accessing the mgmt fields in mt76_connac2_mac_write_txwi_80211 in order to avoid a possible oob access.

CVE-2026-23323 1 Linux 1 Linux Kernel 2026-04-23 7.8 High
In the Linux kernel, the following vulnerability has been resolved: hwmon: (macsmc) Fix regressions in Apple Silicon SMC hwmon driver The recently added macsmc-hwmon driver contained several critical bugs in its sensor population logic and float conversion routines. Specifically: - The voltage sensor population loop used the wrong prefix ("volt-" instead of "voltage-") and incorrectly assigned sensors to the temperature sensor array (hwmon->temp.sensors) instead of the voltage sensor array (hwmon->volt.sensors). This would lead to out-of-bounds memory access or data corruption when both temperature and voltage sensors were present. - The float conversion in macsmc_hwmon_write_f32() had flawed exponent logic for values >= 2^24 and lacked masking for the mantissa, which could lead to incorrect values being written to the SMC. Fix these issues to ensure correct sensor registration and reliable manual fan control. Confirm that the reported overflow in FIELD_PREP is fixed by declaring macsmc_hwmon_write_f32() as __always_inline for a compile test.
CVE-2026-30999 1 Ffmpeg 1 Ffmpeg 2026-04-23 7.5 High
A heap buffer overflow in the av_bprint_finalize() function of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.
CVE-2026-32311 1 Reconurge 1 Flowsint 2026-04-23 9.8 Critical
Flowsint is an open-source OSINT graph exploration tool designed for cybersecurity investigation, transparency, and verification. Flowsint allows a user to create investigations, which are used to manage sketches and analyses. Sketches have controllable graphs, which are comprised of nodes and relationships. The sketches contain information on an OSINT target (usernames, websites, etc) within these nodes and relationships. The nodes can have automated processes execute on them called 'transformers'. A remote attacker can create a sketch, then trigger the 'org_to_asn' transform on an organization node to execute arbitrary OS commands as root on the host machine via shell metacharacters and a docker container escape. Commit b52cbbb904c8013b74308d58af88bc7dbb1b055c appears to remove the code that causes this issue.
CVE-2026-6067 1 Nasm 2 Nasm, Netwide Assembler 2026-04-23 7.5 High
A heap buffer overflow vulnerability exists in the Netwide Assembler (NASM) due to a lack of bounds checking in the obj_directive() function. This vulnerability can be exploited by a user assembling a malicious .asm file, potentially leading to heap memory corruption, denial of service (crash), and arbitrary code execution.
CVE-2026-40303 2 Netfoundry, Openziti 2 Zrok, Zrok 2026-04-23 7.5 High
zrok is software for sharing web services, files, and network resources. Prior to version 2.0.1, endpoints.GetSessionCookie parses an attacker-supplied cookie chunk count and calls make([]string, count) with no upper bound before any token validation occurs. The function is reached on every request to an OAuth-protected proxy share, allowing an unauthenticated remote attacker to trigger gigabyte-scale heap allocations per request, leading to process-level OOM termination or repeated goroutine panics. Both publicProxy and dynamicProxy are affected. Version 2.0.1 patches the issue.
CVE-2026-33414 3 Containers, Microsoft, Podman Project 3 Podman, Windows, Podman 2026-04-23 7.8 High
Podman is a tool for managing OCI containers and pods. Versions 4.8.0 through 5.8.1 contain a command injection vulnerability in the HyperV machine backend in pkg/machine/hyperv/stubber.go, where the VM image path is inserted into a PowerShell double-quoted string without sanitization, allowing $() subexpression injection. Because PowerShell evaluates subexpressions inside double-quoted strings before executing the outer command, an attacker who can control the VM image path through a crafted machine name or image directory can execute arbitrary PowerShell commands with the privileges of the Podman process. On typical Windows installations this means SYSTEM-level code execution, and only Windows is affected as the code is exclusive to the HyperV backend. This issue has been patched in version 5.8.2.
CVE-2026-40520 1 Freepbx 1 Api 2026-04-23 7.2 High
FreePBX api module version 17.0.8 and prior contain a command injection vulnerability in the initiateGqlAPIProcess() function where GraphQL mutation input fields are passed directly to shell_exec() without sanitization or escaping. An authenticated user with a valid bearer token can send a GraphQL moduleOperations mutation with backtick-wrapped commands in the module field to execute arbitrary commands on the underlying host as the web server user.
