A vulnerability was found in Linux Kernel where refcount leak in llcp_sock_bind() causing use-after-free which might lead to privilege escalations.

A vulnerability was found in Linux Kernel, where a refcount leak in llcp_sock_connect() causing use-after-free which might lead to privilege escalations.

A memory leak vulnerability was found in Linux kernel in llcp_sock_connect

A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space

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.

An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations.

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661.

The snapshot feature in Grafana 6.7.3 through 7.4.1 can allow an unauthenticated remote attackers to trigger a Denial of Service via a remote API call if a commonly used configuration is set.

Grafana Enterprise 7.2.x and 7.3.x before 7.3.10 and 7.4.x before 7.4.5 allows a dashboard editor to bypass a permission check concerning a data source they should not be able to access.

The team sync HTTP API in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5 has an Incorrect Access Control issue. On Grafana instances using an external authentication service and having the EditorsCanAdmin feature enabled, this vulnerability allows any authenticated user to add external groups to any existing team. This can be used to grant a user team permissions that the user isn't supposed to have.

One of the usage insights HTTP API endpoints in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5 is accessible without any authentication. This allows any unauthenticated user to send an unlimited number of requests to the endpoint, leading to a denial of service (DoS) attack against a Grafana Enterprise instance.
