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% 109
KEV PoC
CVE-2025-24983 A use-after-free vulnerability in the Windows Win32 Kernel Subsystem enables local privilege escalation from authorized user to SYSTEM level. This KEV-listed vulnerability (CVE-2025-24983) requires the attacker to win a race condition but has been actively exploited in targeted attacks. Microsoft has released patches for all supported Windows versions. HIGH 7.0 0.7% 86
KEV
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
PoC
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
PoC No patch
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
PoC No patch
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
PoC
CVE-2026-23873 HUSTOJ online judge system has a CSV injection vulnerability in all versions that allows code execution through crafted submissions exported to spreadsheets. CRITICAL 9.0 0.0% 65
PoC No patch
CVE-2025-66210 A command injection vulnerability in Coolify's Database Import functionality allows authenticated users with application/service management permissions to execute arbitrary system commands as root on managed servers. The vulnerability stems from unsanitized database names being passed directly to shell commands, enabling full remote code execution. A public proof-of-concept exploit is available, and with an EPSS score of 0.41% (61st percentile), this represents a moderate real-world exploitation risk for organizations using vulnerable Coolify versions. HIGH 8.8 0.4% 64
PoC No patch
CVE-2025-2073 Out-of-Bounds Read in netfilter/ipset in Linux Kernel ChromeOS [6.1, 5.15, 5.10, 5.4, 4.19] allows a local attacker with low privileges to trigger an out-of-bounds read, potentially leading to. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available. HIGH 8.8 0.1% 64
PoC No patch
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% 64
PoC
CVE-2026-27212 Prototype pollution in Swiper versions 6.5.1 through 12.1.1 allows local authenticated attackers to manipulate Object.prototype through improperly validated user input, enabling authentication bypass, denial of service, and remote code execution. Public exploit code exists for this vulnerability, which affects applications on Linux and Windows using Node.js or Bun runtimes. A patch is available and should be applied immediately to affected systems processing untrusted input. HIGH 7.8 0.1% 59
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% 59
PoC
CVE-2025-21704 In the Linux kernel, the following vulnerability has been resolved: usb: cdc-acm: Check control transfer buffer size before access If the first fragment is shorter than struct usb_cdc_notification,. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available. HIGH 7.8 0.0% 59
PoC
CVE-2026-23233 F2FS swapfile memory corruption in Linux kernel 6.6+ allows local attackers with user privileges to cause data corruption through improper physical block mapping when using fragmented swapfiles smaller than the F2FS section size. Public exploit code exists for this vulnerability, and attackers can trigger dm-verity corruption errors or F2FS node corruption leading to system crashes and data loss. No patch is currently available. HIGH 7.8 0.0% 59
