{"id":"USN-5096-1","summary":"linux-oem-5.13 vulnerabilities","details":"Valentina Palmiotti discovered that the io_uring subsystem in the Linux\nkernel could be coerced to free adjacent memory. A local attacker could use\nthis to execute arbitrary code. (CVE-2021-41073)\n\nBenedict Schlueter discovered that the BPF subsystem in the Linux kernel\ndid not properly protect against Speculative Store Bypass (SSB) side-\nchannel attacks in some situations. A local attacker could possibly use\nthis to expose sensitive information. (CVE-2021-34556)\n\nPiotr Krysiuk discovered that the BPF subsystem in the Linux kernel did not\nproperly protect against Speculative Store Bypass (SSB) side-channel\nattacks in some situations. A local attacker could possibly use this to\nexpose sensitive information. (CVE-2021-35477)\n\nMurray McAllister discovered that the joystick device interface in the\nLinux kernel did not properly validate data passed via an ioctl(). A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code on systems with a joystick device\nregistered. (CVE-2021-3612)\n\nIt was discovered that the tracing subsystem in the Linux kernel did not\nproperly keep track of per-cpu ring buffer state. A privileged attacker\ncould use this to cause a denial of service. (CVE-2021-3679)\n\nIt was discovered that the Option USB High Speed Mobile device driver in\nthe Linux kernel did not properly handle error conditions. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash) or possibly execute arbitrary code. (CVE-2021-37159)\n\nAlois Wohlschlager discovered that the overlay file system in the Linux\nkernel did not restrict private clones in some situations. An attacker\ncould use this to expose sensitive information. (CVE-2021-3732)\n\nIt was discovered that the Virtio console implementation in the Linux\nkernel did not properly validate input lengths in some situations. A local\nattacker could possibly use this to cause a denial of service (system\ncrash). (CVE-2021-38160)\n\nIt was discovered that the BPF subsystem in the Linux kernel contained an\ninteger overflow in its hash table implementation. A local attacker could\nuse this to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2021-38166)\n\nMichael Wakabayashi discovered that the NFSv4 client implementation in the\nLinux kernel did not properly order connection setup operations. An\nattacker controlling a remote NFS server could use this to cause a denial\nof service on the client. (CVE-2021-38199)\n\nIt was discovered that the Sun RPC implementation in the Linux kernel\ncontained an out-of-bounds access error. A remote attacker could possibly\nuse this to cause a denial of service (system crash). (CVE-2021-38201)\n\nIt was discovered that the NFS server implementation in the Linux kernel\ncontained an out-of-bounds read when the trace even framework is being used\nfor nfsd. A remote attacker could possibly use this to cause a denial of\nservice (system crash). (CVE-2021-38202)\n\nNaohiro Aota discovered that the btrfs file system in the Linux kernel\ncontained a race condition in situations that triggered allocations of new\nsystem chunks. A local attacker could possibly use this to cause a denial\nof service (deadlock). (CVE-2021-38203)\n\nIt was discovered that the MAX-3421 host USB device driver in the Linux\nkernel did not properly handle device removal events. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2021-38204)\n\nIt was discovered that the Xilinx 10/100 Ethernet Lite device driver in the\nLinux kernel could report pointer addresses in some situations. An attacker\ncould use this information to ease the exploitation of another\nvulnerability. (CVE-2021-38205)\n\nIt was discovered that the ext4 file system in the Linux kernel contained a\nrace condition when writing xattrs to an inode. A local attacker could use\nthis to cause a denial of service or possibly gain administrative\nprivileges.
