USN-5540-1: Linux kernel vulnerabilities Liu Jian discovered that the IGMP protocol implementation in the Linux kernel contained a race condition, 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-2022-20141) It was discovered that the USB gadget subsystem in the Linux kernel did not properly validate interface descriptor requests. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-25258) It was discovered that the Remote NDIS (RNDIS) USB gadget implementation in the Linux kernel did not properly validate the size of the RNDIS_MSG_SET command. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-25375) Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel did not properly perform data validation. A local attacker could use this [ more… ]

USN-5541-1: Linux kernel (Azure) vulnerabilities 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. (CVE-2021-4197) 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 (system crash) or possibly execute arbitrary code. (CVE-2022-1011) Duoming Zhou discovered that the 6pack protocol implementation in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-1198) 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 [ more… ]
