🛡️ USN-6084-1 — linux-gcp-4.15

linux-gcp-4.15, linux-oracle vulnerabilities

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)

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 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)
