Summary
linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities
Details

Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information. (CVE-2023-20593)

Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-31085)

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)

It was discovered that the USB ENE card reader driver in the Linux kernel did not properly allocate enough memory when processing the storage device boot blocks. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-45862)

Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb) Ethernet driver in the Linux kernel did not properly validate received frames that are larger than the set MTU size, leading to a buffer overflow vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-45871)

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)

A local\nprivileged attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-31085)\n\nLucas Leong discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate some attributes passed from userspace. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly expose sensitive information (kernel memory). (CVE-2023-39189)\n\nSunjoo Park discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate u32 packets content, leading to an out-of-bounds read\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information.

(CVE-2023-42754)\n\nIt was discovered that the USB ENE card reader driver in the Linux kernel\ndid not properly allocate enough memory when processing the storage device\nboot blocks. A local attacker could use this to cause a denial of service\n(system crash). (CVE-2023-45862)\n\nManfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb)\nEthernet driver in the Linux kernel did not properly validate received\nframes that are larger than the set MTU size, leading to a buffer overflow\nvulnerability. An attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-45871)\n\nBudimir Markovic discovered that the perf subsystem in the Linux kernel did\nnot properly handle event groups, leading to an out-of-bounds write\nvulnerability.
