{"id":"USN-5703-1","summary":"linux-intel-iotg vulnerabilities","details":"Selim Enes Karaduman discovered that a race condition existed in the\nGeneral notification queue implementation of the Linux kernel, leading to a\nuse-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code.\n(CVE-2022-1882)\n\nPawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan\nand Ariel Sabba discovered that some Intel processors with Enhanced\nIndirect Branch Restricted Speculation (eIBRS) did not properly handle RET\ninstructions after a VM exits. A local attacker could potentially use this\nto expose sensitive information. (CVE-2022-26373)\n\nEric Biggers discovered that a use-after-free vulnerability existed in the\nio_uring subsystem in the Linux kernel. A local attacker could possibly use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2022-3176)\n\nIt was discovered that the Netlink Transformation (XFRM) subsystem in the\nLinux kernel contained a reference counting error. A local attacker could\nuse this to cause a denial of service (system crash). (CVE-2022-36879)\n\nJann Horn discovered that the KVM subsystem in the Linux kernel did not\nproperly handle TLB flush operations in some situations. A local attacker\nin a guest VM could use this to cause a denial of service (guest crash) or\npossibly execute arbitrary code in the guest kernel.
