USN-7381-1: Linux kernel (Low Latency) vulnerabilities

Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code...

USN-7380-1 linux-lowlatency vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - RISC-V architecture; - S390 architecture; - x86...

CVE-2023-53018

CVE-2023-53018 affects the Linux kernel Bluetooth stack. If hci_cmd_sync_queue() fails in hci_le_terminate_big() or hci_le_big_terminate(), the memory pointed to by d is not freed, causing a memory leak. A patch adds a release path in the error flow to fix this. Exploitation details are not provi...

CVE-2023-53017

The CVE-2023-53017 entry concerns a memory leak in the Linux kernel Bluetooth stack (hci_sync path). Root cause: in hci_update_adv_data(), if hci_cmd_sync_queue() fails, the allocated inst_ptr was not freed. Mitigation: switch to using ERR_PTR/PTR_ERR to pass the instance to the callback, so no a...
