USN-6088-1: runC vulnerabilities

Read Time:26 Second

It was discovered that runC incorrectly made /sys/fs/cgroup
writable when in rootless mode. An attacker could possibly
use this issue to escalate privileges. (CVE-2023-25809)

It was discovered that runC incorrectly performed access control when
mounting /proc to non-directories. An attacker could possibly use
this issue to escalate privileges. (CVE-2023-27561)

It was discovered that runC incorrectly handled /proc and
/sys mounts inside a container. An attacker could possibly
use this issue to bypass AppArmor, and potentially SELinux.
(CVE-2023-28642)

USN-6085-1: Linux kernel (Raspberry Pi) vulnerabilities

Read Time:2 Minute, 5 Second

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)

Zheng Wang discovered that the Intel i915 graphics driver in the Linux
kernel did not properly handle certain error conditions, leading to a
double-free. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-3707)

Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did
not properly implement speculative execution barriers in usercopy functions
in certain situations. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2023-0459)

It was discovered that the TLS subsystem in the Linux kernel contained a
type confusion vulnerability in some situations. A local attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-1075)

It was discovered that the Reliable Datagram Sockets (RDS) protocol
implementation in the Linux kernel contained a type confusion vulnerability
in some situations. An attacker could use this to cause a denial of service
(system crash). (CVE-2023-1078)

Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel
did not properly initialize some data structures. A local attacker could
use this to expose sensitive information (kernel memory). (CVE-2023-1513)

It was discovered that the Android Binder IPC subsystem in the Linux kernel
did not properly validate inputs in some situations, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-20938)

It was discovered that a use-after-free vulnerability existed in the iSCSI
TCP implementation in the Linux kernel. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2023-2162)

It was discovered that the NET/ROM protocol implementation in the Linux
kernel contained a race condition in some situations, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-32269)

Duoming Zhou discovered that a race condition existed in the infrared
receiver/transceiver driver in the Linux kernel, leading to a use-after-
free vulnerability. A privileged attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-1118)
