Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2026-31431 | Memory corruption in Linux kernel's algif_aead cryptographic interface allows local authenticated users to achieve arbitrary kernel memory read/write, leading to privilege escalation to root. The vulnerability stems from improper handling of in-place operations introduced in commit 72548b093ee3, affecting kernel versions from 4.14 through 6.19.x. Multiple public exploit codes exist including proof-of-concept demonstrations from security researchers, with EPSS score of 0.01% indicating currently low widespread exploitation likelihood despite POC availability. | HIGH | 7.8 | 0.0% | 134 |

| CVE-2026-53362 | Heap out-of-bounds write in the Linux kernel's IPv6 stack (__ip6_append_data) lets a local unprivileged user corrupt kernel memory by sending data through a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. On the paged-allocation path the linear skb area is undersized by 'fraggap' bytes while pagedlen is overstated by the same amount, so the copy writes past skb->end into the trailing skb_shared_info. No public exploit is identified at time of analysis and EPSS is low (0.18%, 7th percentile), but the flaw is locally triggerable without special privileges and the vendor has released fixes. | HIGH | 7.8 | 0.2% | 109 |
KEV

|
| CVE-2026-43284 | Use-after-free in Linux kernel ESP (IPsec) allows local authenticated attackers to decrypt shared memory fragments improperly, potentially exposing encrypted network traffic or causing memory corruption. Affects kernel versions 6.5+ where MSG_SPLICE_PAGES can attach pipe pages directly to UDP socket buffers. The IPv4/IPv6 datagram paths fail to mark spliced pages as shared, causing ESP input decryption to modify memory not privately owned by the packet buffer. Public exploit code exists (POC available on GitHub), EPSS score is low (0.01%) indicating limited widespread exploitation risk, and vendor patches are available across affected stable kernel branches (6.6.138, 6.12.87, 6.18.28, 7.0.5). | HIGH | 8.8 | 0.0% | 89 |
PoC
|
| CVE-2026-46300 | Local privilege escalation in Linux kernel XFRM ESP-in-TCP subsystem (Fragnesia vulnerability) allows authenticated local attackers to overwrite kernel memory structures by exploiting arbitrary byte writes into the kernel page cache of read-only files. CVSS score of 7.8 reflects high impact across confidentiality, integrity, and availability. Low attack complexity (AC:L) and no user interaction requirement (UI:N) make this exploitable by any local user with basic privileges. No confirmed active exploitation (not in CISA KEV) or public proof-of-concept identified at time of analysis, but the specific vulnerability name 'Fragnesia' suggests coordinated disclosure with security research community. | HIGH | 7.8 | 0.0% | 84 |
PoC
|
| CVE-2026-43500 | Buffer overflow in Linux kernel rxrpc subsystem allows local authenticated attackers to achieve arbitrary code execution with kernel privileges. The vulnerability stems from improper handling of shared fragment memory in DATA and RESPONSE packet processing, where the kernel fails to unshare externally-owned page fragments before in-place decryption operations. This creates a buffer overflow condition (CWE-787) exploitable by local users with low privileges. Patches are available for kernel versions 6.18.29, 7.0.6, and 7.1-rc3. EPSS and KEV status not provided in available data. | HIGH | 7.8 | 0.0% | 84 |
PoC
|
| CVE-2026-43501 | Out-of-bounds heap write in the Linux kernel's IPv6 RPL Source Routing Header (SRH) processing path allows local attackers with raw IPv6 socket access to corrupt memory beyond the skb buffer. The flaw in ipv6_rpl_srh_rcv() occurs when a recompressed SRH grows larger than the received one and consumes unchecked headroom, causing skb_mac_header_rebuild() to wrap a u16 offset and trigger a ~64KiB out-of-bounds memmove. EPSS is very low (0.02%) and no public exploit identified at time of analysis, but the bug is reachable from unprivileged userspace via a single crafted AF_INET6/SOCK_RAW packet over loopback per the reporter's KASAN reproduction. | CRITICAL | 9.8 | 0.0% | 69 |
PoC
|
| CVE-2026-43494 | Local privilege escalation potential in the Linux kernel's RDS (Reliable Datagram Sockets) subsystem stems from a double-free condition triggered when zerocopy page pinning fails during sendmsg() operations. The flaw, introduced in Linux 4.17, allows local authenticated users to corrupt kernel memory by exploiting an error path in rds_message_zcopy_from_user() that fails to reset op_nents, causing rds_message_purge() to free pages that were already released. Publicly available exploit code exists, though EPSS scoring is very low (0.02%) and the issue is not listed in CISA KEV. | HIGH | 7.8 | 0.0% | 69 |
PoC
|
| CVE-2026-46333 | Local privilege escalation in the Linux kernel ptrace subsystem allows authenticated users to bypass the traditional capability-dropping security model when accessing kernel thread details via PTRACE_MODE_READ_FSCREDS checks. The flaw stems from get_dumpable() logic returning misleading values for tasks without an associated memory map (mm), enabling uid-0 processes that have dropped capabilities to still read sensitive kernel thread information. Publicly available exploit code exists (referenced in OSS-security and a GitHub PoC against ssh-keysign), though EPSS scoring (0.02%) indicates low likelihood of widespread exploitation. | HIGH | 7.1 | 0.0% | 66 |
PoC
|
| CVE-2026-53359 | Local privilege escalation and host memory corruption in the Linux kernel's KVM x86 shadow paging (MMU) subsystem allows a low-privileged actor with control over a guest/VMM to trigger a use-after-free in the host kernel. The flaw is an incomplete fix for commit 0cb2af2ea66ad: kvm_mmu_get_child_sp() reuses a shadow page without comparing its role, so a stale rmap entry survives after a memslot is dropped and the shadow page is freed, and later gfn walks dereference a pointer into freed memory. A public proof-of-concept exists (flagged by Italy's ACN/CSIRT) and SSVC rates technical impact as total, but it is not on CISA KEV and EPSS is low (0.18%), indicating no confirmed widespread active exploitation. | HIGH | 8.8 | 0.2% | 64 |
PoC
|
| CVE-2026-82017 | Boot registry parameter injection in IGEL OS 12 (before 12.7.6) and IGEL OS 11 (before 11.11.150) allows an attacker with physical access to execute arbitrary Linux kernel command-line parameters by writing to an unencrypted, unsigned configuration partition that the signed bootloader reads at startup. The attack is particularly dangerous because it does not alter the measured boot code path, meaning TPM PCR attestation does not detect the tampering - effectively defeating the trust assumptions of the secure boot and full-disk encryption stack. A publicly available exploit script and a DEF CON 34 presentation detail the technique; no CISA KEV listing has been issued at time of analysis, indicating exploitation has not been confirmed at scale. | HIGH | 8.6 | 0.2% | 63 |
PoC
|
| CVE-2026-68432 | Privilege escalation in the Linux kernel's vxlan subsystem allows a local user holding CAP_NET_ADMIN in a vxlan device's network namespace to rewrite underlay configuration in a separate, more privileged namespace where they lack that capability. The flaw in vxlan_changelink() affects multiple stable kernel branches (6.6.x, 6.12.x, 6.18.x, 7.1.x, and 7.2-rc) and is most impactful in multi-tenant container or cloud environments where vxlan devices span namespace boundaries - a common topology in Kubernetes and OpenStack deployments. With an EPSS score of 17% and no public exploit or CISA KEV listing confirmed at time of analysis, this is an elevated-risk local privilege escalation requiring prompt patching on affected containerized infrastructure. | HIGH | 8.8 | 17.0% | 61 |
|
| CVE-2026-46331 | Local privilege escalation potential in the Linux kernel's net/sched traffic-control subsystem arises from a partial copy-on-write (COW) miss in the pedit action (tcf_pedit_act), where skb_ensure_writable() is sized using tcfp_off_max_hint before the per-key loop and fails to account for the runtime header offset added by typed keys, leaving part of the write region un-COW'd and causing page cache corruption. A local low-privileged attacker able to install tc pedit rules (CAP_NET_ADMIN, obtainable in user namespaces on many distros) can corrupt shared page-cache memory, with CVSS 7.8 reflecting high confidentiality, integrity, and availability impact. Publicly available exploit code exists, though EPSS is low at 0.14% (4th percentile) and the issue is not on CISA KEV. | HIGH | 7.8 | 0.1% | 59 |
PoC
|
| CVE-2026-43038 | Memory corruption in Linux kernel IPv6 ICMP error handling allows remote unauthenticated attackers to potentially achieve code execution or information disclosure. The vulnerability arises from incomplete control block (CB) sanitization when converting IPv4 ICMP errors to ICMPv6, enabling forged CIPSO options in outer IPv4 packets to manipulate inner IPv6 packet parsing. This can trigger out-of-bounds memory access extending into skb_shared_info structures. Despite CVSS 9.8 critical rating, EPSS exploitation probability is extremely low (0.02%, 7th percentile), no public exploit code exists, and CISA has not listed this as actively exploited. Patches are available across all supported kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). | CRITICAL | 9.8 | 0.0% | 59 |
|
| CVE-2026-31581 | Local privilege escalation via a use-after-free in the Linux kernel's ALSA driver for the TerraTec DMX 6Fire USB audio interface (sound/usb/6fire) lets a local attacker corrupt freed slab memory when the device is disconnected. The flaw is a CVSS 7.8 (CVSS:3.1 AV:L/PR:L) memory-corruption bug with publicly available proof-of-concept code, though EPSS is negligible (0.02%) and it is not on CISA KEV. usb6fire_chip_abort() writes chip->card = NULL after snd_card_free_when_closed() may have already freed the card-owned chip struct, giving an attacker a window to hijack freed kernel memory. | HIGH | 7.8 | 0.0% | 59 |
PoC
|
| CVE-2026-68433 | Uninitialized memory read in the Linux kernel's libceph client library exposes stale kernel buffer contents and risks system instability on Ceph-connected hosts. The flaw exists in handle_get_version_reply(), which incorrectly uses msg->front_alloc_len - the allocated buffer size - as the decode boundary instead of msg->front.iov_len, the count of bytes actually received. A truncated MON_GET_VERSION_REPLY from a malicious or compromised Ceph monitor therefore passes the ceph_decode_need() guard and reads a second u64 from leftover bytes of a prior message, constituting an out-of-bounds read of uninitialized kernel memory. No public exploit has been identified at time of analysis, but the 16% EPSS score is elevated for a kernel library flaw and warrants prompt patching on Ceph-client deployments. | HIGH | 8.6 | 16.0% | 59 |
