The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel.
An unspecified vulnerability in Java SE related to the VM component could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.
An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients.
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the getrecursedatalength() function of the pcre2jitcompile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compilexclassmatchingpath() function of the pcre2jitcompile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 11.0.13; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
An integer overflow flaw was found in the fix applied to the BMPImageReader class implementation in the ImageIO component of OpenJDK to address the CVE-2021-35586 (bug 2015308) issue. This issue could allow a specially-crafted BMP image to bypass previously applied protection and cause a Java application to allocate an excessive amount of memory when opened.
An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
An issue was discovered in the Linux kernel before 5.0.19. The XFRM subsystem has a use-after-free, related to an xfrmstatefini panic, aka CID-dbb2483b2a46.
A flaw was found in kernel/bpf/verifier.c in BPF in the Linux kernel. An incorrect limit is enforced for pointer arithmetic operations which can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
The block subsystem in the Linux kernel before 5.2 has a use-after-free that can lead to arbitrary code execution in the kernel context and privilege escalation, aka CID-c3e2219216c9. This is related to blkmqfreerqs and blkcleanupqueue.
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.
Element Plug-in for vCenter Server incorporates SpringBoot Framework. SpringBoot Framework versions prior to 1.3.2 are susceptible to a vulnerability which when successfully exploited could lead to Remote Code Execution. All versions of Element Plug-in for vCenter Server, Management Services versions prior to 2.17.56 and Management Node versions through 12.2 contain vulnerable versions of SpringBoot Framework.
An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch//xen/p2m.c and drivers/xen/gntdev.c.
A flaw was found in the Linux kernel. Wrong locking in the AFVSOCK socket can cause a local privilege escalation, bypassing SMEP and SMAP. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
selinuxeditcopytfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudoedit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
Element OS versions prior to 1.8P1 and 12.2 are susceptible to a vulnerability that could allow an unauthenticated remote attacker to perform arbitrary code execution.
An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
A Null Pointer Dereference vulnerability exists in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.34, in bfdelfgetsymbolversionstring, as demonstrated in nm-new, that can cause a denial of service via a crafted file.

A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
getgatepage 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 processvmreadv(), aka CID-9fa2dd946743.
An issue was discovered in splithugepmd in mm/hugememory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1.
NTP is vulnerable to a denial of service, caused by an issue when relying on unauthenticated IPv4 time sources in ntpd. By predicting transmit timestamps for use in spoofed packets, a remote attacker could exploit this vulnerability to cause the daemon to crash or system time change.
