CVE-2022-27499 2.5 LOW 1 PoC Analysis EPSS 0.03

Premature release of resource during expected lifetime in the Intel(R) SGX SDK software may allow a privileged user to potentially enable information disclosure via local access.

CWE-672 Nov 11, 2022

CVE-2020-25221 7.8 HIGH 1 PoC EPSS 0.00

get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.

CVE-2020-24030 9.8 CRITICAL 2 PoCs Analysis EPSS 0.01

ForLogic Qualiex v1 and v3 has weak token expiration. This allows remote unauthenticated privilege escalation and access to sensitive data via token reuse. NOTE: as of 2025-10-14, the Supplier's perspective is that this is "not exploitable in the current implementation. Tokens are properly expired, invalidated, and bound to session context. Attempts to alter the token payload to extend its validity do not affect server-side validation."

CVE-2019-17638 9.4 CRITICAL 1 PoC Analysis EPSS 0.31

In Eclipse Jetty, versions 9.4.27.v20200227 to 9.4.29.v20200521, in case of too large response headers, Jetty throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and while thread1 is about to use the ByteBuffer to write response1 data, thread2 fills the ByteBuffer with other data. Thread1 then proceeds to write the buffer that now contains different data. This results in client1, which issued request1 seeing data from another request or response which could contain sensitive data belonging to client2 (HTTP session ids, authentication credentials, etc.). If the Jetty version cannot be upgraded, the vulnerability can be significantly reduced by configuring a responseHeaderSize significantly larger than the requestHeaderSize (12KB responseHeaderSize and 8KB requestHeaderSize).

CWE-675 Jul 09, 2020

CVE-2020-11027 6.1 MEDIUM 1 PoC Analysis EPSS 0.43

In affected versions of WordPress, a password reset link emailed to a user does not expire upon changing the user password. Access would be needed to the email account of the user by a malicious party for successful execution. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).

CWE-640 Apr 30, 2020

CVE-2019-15794 7.1 HIGH 1 PoC Analysis EPSS 0.00

Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow.

CWE-672 Apr 24, 2020

CVE-2019-15791 7.1 HIGH 1 PoC Analysis EPSS 0.00

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow.

CWE-191 Apr 24, 2020

CVE-2009-3547 7.0 HIGH EXPLOITED 5 PoCs Analysis EPSS 0.03

Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.
