In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.

Potential speculative code store bypass in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution of overwritten instructions, may cause an incorrect speculation and could result in data leakage.

Observable response discrepancy in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.

Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length.

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been detected in security_fips_decrypt in libfreerdp/core/security.c due to an uninitialized value.

Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Zone). The supported version that is affected is 11.3. Easily "exploitable" vulnerability allows low privileged attacker with logon to the infrastructure where Solaris executes to compromise Solaris. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Solaris accessible data. CVSS 3.0 Base Score 3.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).
