Summary
linux-azure vulnerabilities
Details

It was discovered that a race condition existed in the Android Binder IPC subsystem 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 execute arbitrary code. (CVE-2022-20421)

David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

It was discovered that the Intel 740 frame buffer driver in the Linux kernel contained a divide by zero vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3061)

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)

Gwnaun Jung discovered that the SFB packet scheduling implementation 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-2022-3586)

It was discovered that the NILFS2 file system implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3646)

Hyunwoo Kim discovered that an integer overflow vulnerability existed in the PXA3xx graphics driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-39842)

It was discovered that a race condition existed in the EFI capsule loader driver 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 execute arbitrary code. (CVE-2022-40307)

Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver 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-2022-4095)

It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750)

Jann Horn discovered a race condition existed in the Linux kernel when unmapping VMAs in certain situations, resulting in possible use-after-free vulnerabilities. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-39188)

(CVE-2022-3061)\n\nIt was discovered that the sound subsystem in the Linux kernel contained a\nrace condition in some situations. A local attacker could use this to cause\na denial of service (system crash). (CVE-2022-3303)\n\nGwnaun Jung discovered that the SFB packet scheduling implementation in the\nLinux kernel contained a use-after-free vulnerability. A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2022-3586)\n\nIt was discovered that the NILFS2 file system implementation in the Linux\nkernel did not properly deallocate memory in certain error conditions. An\nattacker could use this to cause a denial of service (memory exhaustion).\n(CVE-2022-3646)\n\nHyunwoo Kim discovered that an integer overflow vulnerability existed in\nthe PXA3xx graphics driver in the Linux kernel. A local attacker could\npossibly use this to cause a denial of service (system crash).\n(CVE-2022-39842)\n\nIt was discovered that a race condition existed in the EFI capsule loader\ndriver in the Linux kernel, leading to a use-after-free vulnerability. A\nlocal attacker could use this to cause a denial of service (system crash)\nor possibly execute arbitrary code. (CVE-2022-40307)\n\nZheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless\ndriver in the Linux kernel contained a use-after-free vulnerability. A\nlocal attacker could use this to cause a denial of service (system crash)\nor possibly execute arbitrary code. (CVE-2022-4095)\n\nIt was discovered that the USB monitoring (usbmon) component in the Linux\nkernel did not properly set permissions on memory mapped in to user space\nprocesses. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2022-43750)\n\nJann Horn discovered a race condition existed in the Linux kernel when\nunmapping VMAs in certain situations, resulting in possible use-after-free\nvulnerabilities. A local attacker could possibly use this to cause a denial\nof service (system crash) or execute arbitrary code. (CVE-2022-39188)\n",
