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 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.
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.

An issue was discovered in mm/mmap.c in the Linux kernel before 5.7.11. There is a race condition between certain expand functions (expanddownwards and expandupwards) and page-table free operations from an munmap call, aka CID-246c320a8cfe.
A flaw was found in the CPU microarchitecture where a local attacker is able to abuse a timing issue which may allow them to infer internal architectural state from previous executions on the CPU.
A flaw was found in the implementation of Intel Advanced Vector Extensions (AVX) where a local authenticated attacker with the ability to execute AVX instructions is able to gather AVX register state from previous AVX executions.
This could allow information disclosure of AVX register state.
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
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.
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.
A flaw was found in the way the mwifiexcmdappendvsietlv() in Linux kernel's Marvell WiFi-Ex driver handled vendor specific information elements. A local user could use this flaw to escalate their privileges on the system.
In the Linux kernel before 5.0.3, a memory leak exits in hsrdevfinalize() in net/hsr/hsrdevice.c if hsraddport fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.
GNU binutils gold gold v1.11-v1.16 (GNU binutils v2.21-v2.31.1) is affected by: Improper Input Validation, Signed/Unsigned Comparison, Out-of-bounds Read. The impact is: Denial of service. The component is: gold/fileread.cc:497, elfcpp/elfcppfile.h:644. The attack vector is: An ELF file with an invalid eshoff header field must be opened.
An issue was discovered in getvdevportnodeinfo in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdupconst of nodeinfo->vdevport.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
A vulnerability was found in NTP. A security issue which enables an off-path attacker to prevent ntpd from synchronizing with NTP servers not using authentication. A server mode packet with spoofed source address sent to the client ntpd causes the next transmission to be rescheduled, even if the packet doesn't have a valid origin timestamp. If the packet is sent to the client frequently enough, it will stop polling the server and not be able to synchronize with it.
The Siemens R3964 line discipline driver in drivers/tty/nr3964.c in the Linux kernel before 5.0.8 has multiple race conditions.
A flaw was reported in kernel TCP subsystem while calculating a packet round trip time, when a sysctl parameter (/proc/sys/net/ipv4/tcpminrttwlen) when is set wrongly. This causes an integer over flaw which can lead to a Denial Of Service (DOS) attack.

An issue was discovered in aiopoll() in fs/aio.c in the Linux kernel through 5.0.4. A file may be released by aiopollwake() if an expected event is triggered immediately (e.g., by the close of a pair of pipes) after the return of vfspoll(), and this will cause a use-after-free.
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in setupgroup in elf.c.
