Linux Kernel Use-After-Free Vulnerability — Linux Kernel contains a use-after-free vulnerability in the nft_object, allowing local attackers to escalate privileges. Listed in the CISA KEV catalog (added 2024-06-26) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~10%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Linux Kernel: Apply updates per vendor instructions or discontinue use of the product if updates are unavailable. CISA set a federal remediation due date of 2024-07-17. After patching, verify the vulnerable path is no longer reachable before closing the finding.

- CVE-2026-109618CRIT 9.8KEVEPSS 100%
PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request. Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).
- CVE-2019-0708CRIT 9.8KEVEPSS 100%
A remote code execution vulnerability exists in Remote Desktop Services formerly known as Terminal Services when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests, aka 'Remote Desktop Services Remote Code Execution Vulnerability'.
- CVE-2026-109619HIGH 8.1KEVEPSS 100%
PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).

Use-after-free vulnerability in Microsoft Internet Explorer 6, 7, and 8 allows remote attackers to execute arbitrary code via vectors related to Cascading Style Sheets (CSS) token sequences and the clip attribute, aka an "invalid flag reference" issue or "Uninitialized Memory Corruption Vulnerability," as exploited in the wild in November 2010.
