USN-6252-1

It was discovered that the ext4 file system implementation in the Linux kernel contained a use-after-free vulnerability. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service (system crash). (CVE-2022-1184)

It was discovered that the sound subsystem in the Linux kernel contained a race condition in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3303)

It was discovered that a race condition existed in the btrfs file system implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1611)

It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670)

It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2023-1859)

It was discovered that the ST NCI NFC driver did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1990)

It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124)

It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of-...
