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

Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle locking during table_clear() operations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2023-2269)

It was discovered that a use-after-free vulnerability existed in the HFS+ file system implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-2985)

It was discovered that the DVB Core driver in the Linux kernel did not properly handle locking events in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2023-31084)

It was discovered that the virtual terminal driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-3567)

It was discovered that the Quick Fair Queueing network scheduler implementation in the Linux kernel contained 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-2023-3611)

It was discovered that the network packet classifier with netfilter/firewall marks implementation in the Linux kernel did not properly handle reference counting, 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-2023-3776)
