A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time

A heap-based overflow vulnerability in Trellix Agent (Windows and Linux) version 5.7.8 and earlier, allows a remote user to alter the page heap in the macmnsvc process memory block resulting in the service becoming unavailable.

A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.

A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work.

An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2misc.c has an out-of-bounds read and OOPS for SMB2_TREE_CONNECT.

Windows DNS Server Denial of Service Vulnerability

IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5 under certain circumstances could allow an authenticated user to the database to cause a denial of service when a statement is run on columnar tables. IBM X-Force ID: 273393.

Null pointer dereference in Windows Local Security Authority (LSA) allows an authorized attacker to deny service over a network.
