An exploitable vulnerability exists in the way Pixar OpenUSD 20.05 handles parses certain encoded types. A specially crafted malformed file can trigger an arbitrary out of bounds memory access in TfToken Type Index. This vulnerability could be used to bypass mitigations and aid further exploitation. To trigger this vulnerability, the victim needs to access an attacker-provided malformed file.

A heap overflow vulnerability exists in Pixar OpenUSD 20.05 when the software parses compressed sections in binary USD files. A specially crafted USDC file format path jumps decompression heap overflow in a way path jumps are processed. To trigger this vulnerability, the victim needs to open an attacker-provided malformed file.

A heap overflow vulnerability exists in the Pixar OpenUSD 20.05 parsing of compressed string tokens in binary USD files. A specially crafted malformed file can trigger a heap overflow which can result in out of bounds memory access which could lead to information disclosure. This vulnerability could be used to bypass mitigations and aid further exploitation. To trigger this vulnerability, victim needs to access an attacker-provided malformed file.

An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.

IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could allow a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances. IBM X-Force ID: 189296.

Improper input validation in the Auto-Discovery component of Nagios XI before 5.7.5 allows an authenticated attacker to execute remote code.

A heap overflow vulnerability exists in Pixar OpenUSD 20.05 when the software parses compressed sections in binary USD files. To trigger this vulnerability, the victim needs to open an attacker-provided malformed file in an instance USDC file format path element token index.

A heap overflow vulnerability exists in the Pixar OpenUSD 20.05 while parsing compressed value rep arrays in binary USD files. A specially crafted malformed file can trigger a heap overflow, which can result in remote code execution. To trigger this vulnerability, the victim needs to access an attacker-provided malformed file.

Improper input validation in BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.

Improper conditions check in Intel BIOS platform sample code for some Intel(R) Processors before may allow a privileged user to potentially enable escalation of privilege via local access.
