Out-of-bounds write in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.
An issue was discovered in the Linux kernel through 5.18.14. xfrmexpandpolicies in net/xfrm/xfrmpolicy.c can cause a refcount to be dropped twice.
A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the crehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script.
A flaw was found in OpenSSL. The crehash script does not properly sanitize shell meta-characters to prevent command injection. Some operating systems distribute this script in a manner where it is automatically executed. This flaw allows an attacker to execute arbitrary commands with the privileges of the script on these operating systems.
A flaw was found in OpenSSL's Online Certificate Status Protocol (OCSP) response functionality in the signer certificate verification routines. This flaw could result in a linked application falsely believing that an x.509 Digital Certificate is either "good" or "unknown" when revoked and requires that the application use a non-default configuration. This vulnerability leads to an issue with data integrity and confidentiality.
A memory leak flaw was found in OpenSSL, resulting in TLS servers and clients being halted by out-of-memory conditions, leading to a denial of service. An attacker needs to repeat actions continuously to trigger this vulnerability, resulting in a loss of application 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.
A flaw possibility of race condition and incorrect initialization of the process id was found in the Linux kernel child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process.
A use-after-free flaw was observed in blkdevget(), in fs/blockdev.c after a call to blkdevget() fails, and its refcount gets freed/released. This problem may cause a denial of service problem with a special user privilege, and may even lead to a confidentiality issue.
An out-of-bounds write flaw was found in the Linux kernel. A crafted keycode table could be used by drivers/input/input.c to perform the out-of-bounds write. A local user with root access can insert garbage to this keycode table that can lead to out-of-bounds memory access. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in trymergefreespace in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.
A memory leak in the cryptoreportstat() function in crypto/cryptouserstat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering cryptoreportstatalg() failures, aka CID-c03b04dcdba1.
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.
