In the Linux kernel, picknextrtentity() may return a type confused entry, not detected by the BUGON condition, as the confused entry will not be NULL, but listhead.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused schedrtentity,causing memory corruption.
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.

NTP is vulnerable to a denial of service, caused by a memory leak when a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file in ntpd. By sending specially-crafted packets, a remote authenticated attacker could exploit this vulnerability to consume all available memory resources.
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.
A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.
A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system.
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.
