Ubuntu Security Notice 5518-1 - It was discovered that the eBPF implementation in the Linux kernel did not properly prevent writes to kernel objects in BPF_BTF_LOAD commands. A privileged local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 5517-1 - It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 5516-1 - It was discovered that Vim incorrectly handled memory access. An attacker could potentially use this issue to cause the corruption of sensitive information, a crash, or arbitrary code execution.

Ubuntu Security Notice 5515-1 - Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. A local attacker could possibly use this to gain administrative privileges. Jann Horn discovered that the FUSE file system in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5514-1 - It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service. Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 5513-1 - Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code. Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5473-2 - USN-5473-1 updated ca-certificates. This update provides the corresponding update for Ubuntu 16.04 ESM. The ca-certificates package contained outdated CA certificates. This update refreshes the included certificates to those contained in the 2.50 version of the Mozilla certificate authority bundle.

Ubuntu Security Notice 5511-1 - Carlo Marcelo Arenas Belon discovered that an issue related to CVE-2022-24765 still affected Git. An attacker could possibly use this issue to run arbitrary commands as administrator.

Jerryscript v2.4.0 was discovered to contain a stack buffer overflow via the function jerryx_print_unhandled_exception in /util/print.c.

Ubuntu Security Notice 5256-1 - It was discovered that uriparser incorrectly handled certain memory operations. An attacker could use this to cause a denial of service.
