The kernel packages contain the Linux kernel, the core of any Linux operating system. * A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel"s N_TTY line discipline implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivileged, local user could ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel"s floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free arbitrary kernel memory. * It was found that the Linux kernel"s floppy driv ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel"s futex subsystem handled the requeuing of certain Priority Inheritance futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. * A flaw was found in the way the Linux kernel"s floppy driver handled user space provided da ...

A local, unprivileged user could use this flaw to escalate their privileges on the system. * A use-after-free flaw was found in the way the ping_init_sock function of the Linux kernel ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A NULL pointer dereference flaw was found in the rds_iw_laddr_check function in the Linux kernel"s implementation of Reliable Datagram Sockets . A local, unprivileged user could use this flaw to crash the system. * It was found that the Xen hypervisor implementation did not properly clean memory pages previous ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel"s ptrace subsystem allowed a traced process" instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate thei ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A use-after-free flaw was found in the way the ping_init_sock function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. * A NULL pointer dereference flaw was found in the wa ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that Linux kernel"s ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * An out-of-bounds memory access flaw was found in the Linux kernel"s system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. This update also fixes the following bugs ...
