USN-6091-1: Linux kernel vulnerabilities

It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. CVE-2022-27672 Ziming Zhang discovered that the VMware Virtual GPU DR...

Kernel: NULL pointer dereference problem in sctp_sched_dequeue_common

A NULL pointer dereference issue was found in the SCTP network protocol in net/sctp/streamsched.c in the Linux kernel. If streamin allocation fails, streamout is freed, which would be accessed further. This flaw allows a local user to crash the system or potentially cause a denial of service...

EulerOS 2.0 SP9 : kernel (EulerOS-SA-2023-1848)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack...

OESA-2023-1277 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to...

The vulnerability in the implementation of the SCTP protocol in Linux kernel allows a attacker to cause a service failure (to disconnect the connection).

The vulnerability in the implementation of the SCTP protocol net/sctp/smstatefuns.c in the Linux kernel is related to the lack of checking VTAG in the blocks received from the user, and the incorrect ABORT flag used to process these blocks. Exploiting this vulnerability allows a remote attacker t...
