CVE-2021-27365

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGESIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum leng...

kernel: SELinux netlink permission check bypass

A flaw was found in the Linux kernel’s SELinux LSM hook implementation, where it anticipated the skb would only contain a single Netlink message. The hook incorrectly validated the first Netlink message in the skb only, to allow or deny the rest of the messages within the skb with the granted...

CVE-2020-10751

The issue CVE-2020-10751 affects the Linux kernel SELinux LSM hook. It incorrectly validates only the first Netlink message in an skb, causing subsequent messages in the same skb to be granted permissions without further processing. This could enable bypass of SELinux netlink restrictions and, pe...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.7 Description: A flaw in the Linux kernel's SELinux LSM hook implementation allows for insufficient authentication of data. This issue arises because the hook incorrectly assumes that a socket buffer skb...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A flaw was found in inetcskdiagdump in the Linux kernel's module for monitoring the sockets of INET transport protocols. By sending a netlink message with certain bytecode, a local, unprivileged user could cause a denial of service...

kernel: Out-of-bounds access via an XFRM_MSG_MIGRATE xfrm Netlink message

The xfrmmigrate function in the net/xfrm/xfrmpolicy.c file in the Linux kernel built with CONFIGXFRMMIGRATE does not verify if the dir parameter is less than XFRMPOLICYMAX. This allows a local attacker to cause a denial of service out-of-bounds access or possibly have unspecified other impact by...
