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 |
KEV
PoC
|
| 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
PoC
|
| 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-2026-24479 | HUSTOJ online judge has a path traversal vulnerability enabling arbitrary file access on the competition server. | CRITICAL | 9.8 | 0.6% | 85 |
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-2026-26068 | Command injection in emp3r0r C2 framework before 3.21.1. Untrusted agent metadata (Transport, Hostname) injected into commands. PoC and patch available. EPSS 0.61%. | CRITICAL | 9.9 | 0.6% | 70 |

| CVE-2026-29128 | Plaintext daemon credentials in IDC SFX2100 routing config files (zebra, bgpd, ospfd, ripd). CVSS 10.0. PoC available. | CRITICAL | 10.0 | 0.0% | 70 |

| CVE-2021-47796 | Denver SHC-150 Smart WiFi Camera has hardcoded telnet credentials on port 23, providing unauthenticated root shell access. PoC available. | CRITICAL | 9.8 | 0.1% | 69 |

| CVE-2025-40271 | Use-after-free in the Linux kernel's procfs directory-reading path (proc_readdir_de() in fs/proc) allows a local user to trigger a race between directory traversal and concurrent removal of proc entries, corrupting kernel memory. The bug arises because a proc_dir_entry is erased from the subdir red-black tree without clearing the node, so pde_subdir_next() can return a freed node; it was found via stress-ng running getdents against /proc/<pid>/net/dev_snmp6/ while network devices (tun interfaces) are unregistered. Publicly available exploit code exists and a vendor patch is available, but the CVE is not listed in CISA KEV and carries a very low EPSS score (0.05%), indicating no evidence of widespread exploitation. | HIGH | 7.8 | 0.1% | 69 |
PoC
|
| CVE-2026-23111 | A use-after-free vulnerability in the Linux kernel's netfilter nf_tables module allows local attackers with unprivileged access to cause memory corruption and denial of service through an inverted logic check in catchall map element activation during failed transactions. The flaw occurs in nft_map_catchall_activate() which incorrectly processes already-active elements instead of inactive ones, potentially leading to privilege escalation or system crash. No patch is currently available. | HIGH | 7.8 | 0.0% | 69 |
PoC
|
| CVE-2026-23231 | A use-after-free vulnerability in the Linux kernel's netfilter nf_tables chain registration allows local attackers with user privileges to trigger memory corruption and cause a denial of service, potentially leading to privilege escalation. The flaw occurs when hook registration fails during chain addition, allowing concurrent operations to access freed memory without proper RCU synchronization. The vulnerability affects systems running vulnerable Linux kernels with netfilter enabled, and no patch is currently available. | HIGH | 7.8 | 0.0% | 69 |
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-2025-39946 | CVE-2025-39946 is a security vulnerability (CVSS 5.5). Risk factors: public PoC available. Vendor patch is available. | CRITICAL | 9.8 | 0.0% | 69 |
