USN-5139-1: Linux kernel (OEM 5.10) vulnerabilities Ilja Van Sprundel discovered that the SCTP implementation in the Linux kernel did not properly perform size validations on incoming packets in some situations. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2021-3655) It was discovered that the AMD Cryptographic Coprocessor (CCP) driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3744, CVE-2021-3764) It was discovered that the NFC protocol implementation in the Linux kernel contained a use-after-free vulnerability in its NFC Controller Interface (NCI) implementation. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3760) It was discovered that an integer overflow could be triggered in the eBPF implementation in [ more… ]

USN-5138-1: python-py vulnerability The py.path.svnwc component of py (aka python-py) through v1.9.0 contains a regular expression with an ambiguous subpattern that is susceptible to catastrophic backtracing. This could be used by attackers to cause a compute-time denial of service attack by supplying malicious input to the blame functionality. Source: USN-5138-1: python-py vulnerability
