[USN-6548-3] Linux kernel (Oracle) vulnerabilities

Severity High

Affected Packages 13

CVEs 10

Several security issues were fixed in the Linux kernel.

It was discovered that Spectre-BHB mitigations were missing for Ampere
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2023-3006)

It was discovered that the USB subsystem in the Linux kernel contained a
race condition while handling device descriptors in certain situations,
leading to a out-of-bounds read vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2023-37453)

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did
not properly validate some attributes passed from userspace. A local
attacker could use this to cause a denial of service (system crash) or
possibly expose sensitive information (kernel memory). (CVE-2023-39189)

Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did
not properly validate u32 packets content, leading to an out-of-bounds read
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-39192)

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did
not properly validate SCTP data, leading to an out-of-bounds read
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-39193)

Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in
the Linux kernel did not properly handle state filters, leading to an out-
of-bounds read vulnerability. A privileged local attacker could use this to
cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2023-39194)

Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did
not properly handle socket buffers (skb) when performing IP routing in
certain circumstances, leading to a null pointer dereference vulnerability.
A privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-42754)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly handle queue initialization failures in certain
situations, leading to a use-after-free vulnerability. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5178)

Budimir Markovic discovered that the perf subsystem in the Linux kernel did
not properly handle event groups, leading to an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-5717)

It was discovered that the TLS subsystem in the Linux kernel did not
properly perform cryptographic operations in some situations, leading to a
null pointer dereference vulnerability. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-6176)
