Linux Kernel is vulnerable to information leak. It is possible due to a flaw in the `scsi_ioctl` function in `drivers/scsi/scsi_ioctl.c` in the Linux kernel, allowing a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality.

This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A use-after-free flaw was found in the Linux kernel's io_uring subsystem in the way a user sets up a ring with IORING_SETUP_IOPOLL with more than one task completing submissions on this ring. This flaw allows a local user to crash or escalate their privileges on the system. (CVE-2022-1786)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state.
