Incorrect access control in RDP Level 1 on STMicroelectronics STM32F0 series devices allows physically present attackers to extract the device’s protected firmware via a special sequence of Serial Wire Debug (SWD) commands because there is a race condition between full initialization of the SWD interface and the setup of flash protection.
A remote arbitrary file read vulnerability was discovered in some Aruba Instant Access Point (IAP) products in version(s): Aruba Instant 6.5.x: 220.127.116.11 and below; Aruba Instant 8.3.x: 18.104.22.168 and below; Aruba Instant 8.5.x: 22.214.171.124 and below; Aruba Instant 8.6.x: 126.96.36.199 and below; Aruba Instant 8.7.x: 188.8.131.52 and below. Aruba has released patches for Aruba Instant that address this security vulnerability.
A race condition was addressed with additional validation. This issue is fixed in macOS Big Sur 11.2.1, macOS Catalina 10.15.7 Supplemental Update, macOS Mojave 10.14.6 Security Update 2021-002. An application may be able to execute arbitrary code with kernel privileges.
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
