Summary
linux-oem-6.1 vulnerabilities
Details

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)

Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service (paravirtualized device unavailability). (CVE-2023-34324)

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)

Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4244)

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 Quick Fair Queueing scheduler implementation in the Linux kernel did not properly handle network packets in certain conditions, 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-2023-4921)

It was discovered that the SMB network file sharing protocol implementation in the Linux kernel did not properly handle certain error conditions, 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-2023-5345)
