An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
Guest triggered use-after-free in Linux xen-netback A malicious or buggy network PV frontend can force Linux netback to disable the interface and terminate the receive kernel thread associated with queue 0 in response to the frontend sending a malformed packet. Such kernel thread termination will lead to a use-after-free in Linux netback when the backend is destroyed, as the kernel thread associated with queue 0 will have already exited and thus the call to kthreadstop will be performed against a stale pointer.
A flaw was found in the Serialization component of OpenJDK. A reference to an uninitialized class descriptor encountered during object stream deserialization could cause an unexpected exception to be raised when processing an untrusted serialized input.
A CRLF injection flaw was found in the Lightweight HTTP Server component of OpenJDK. The HttpServer implementation did not restrict the use of CR and LF characters in values for HTTP headers, possibly allowing HTTP response splitting attacks.
A regular expression denial of service flaw was found in the Concurrency component of OpenJDK. The use of overly complex regular expressions in java.utils.Scanner could cause a high CPU usage when Scanner was used on parse certain inputs.
A flaw was found in the way the readObject() method of the MethodType class in the Libraries component of OpenJDK checked argument types. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.
A flaw was found in the boundary checks in the java.nio buffer classes in the Libraries component of OpenJDK, where it is bypassed in certain cases. This flaw allows an untrusted Java application or applet o bypass Java sandbox restrictions.
A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. The state machine of the regular expression Parser did not correctly handle empty string nodes in certain cases, which could cause an unexpected exception to be raised when processing a specially crafted regular expression.
A flaw was found in the Serialization component of OpenJDK. The invokeWriteObject() method of the ObjectStreamClass method failed to catch InstantiationError exception during object stream deserialization, which could cause an unexpected exception to be raised when processing an untrusted serialized input.
A flaw was found in the Security component of OpenJDK. It was discovered that the unmarshalKeyInfo() method of the DOMKeyInfoFactory class and the unmarshalXMLSignature() method of the DOMXMLSignatureFactory class could raise exceptions not declared as thrown by these methods when reading key info or XML signature data from XML input.
A flaw was found in the way the TLS implementation in the JSSE component of OpenJDK re-used single null TLS sessions for new TLS connections. A remote attacker could possibly use this flaw to impact availability of a Java application providing TLS server.
A flaw was found in jackson-databind. FasterXML mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was discovered in processing setsockopt IPTSOSETREPLACE (or IP6TSOSETREPLACE) for 32 bit processes on 64 bit systems. This flaw will allow local user to gain privileges or cause a DoS through user name space. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIGUSERNS and CONFIGNETNS and the user is granted elevated privileges.
ext/fts3/fts3snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query.
A crafted request uri-path can cause modproxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
A flaw was found in the Nosy driver in the Linux kernel in versions prior to v5.12-rc6. It allows a device to be inserted twice into a doubly linked list, leading to use-after-free when one of these devices is removed.

An out-of-bounds (OOB) memory write flaw was found in preallocelemsandfreelist in kernel/bpf/stackmap.c in the bpf iin the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an integer overflow, and this could allow a local attacker, with a special user privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information.

An issue was discovered in aspeedlpcctrlmmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes.
A carefully crafted request uri-path can cause modproxyuwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive).
An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.
