hw: Intel GPU blitter manipulation can allow for arbitrary kernel memory write

A flaw was found in the Intel graphics hardware GPU, where a local attacker with the ability to issue commands to the GPU could inadvertently lead to memory corruption and possible privilege escalation. The attacker could use the GPU blitter to perform privilege MMIO operations, not limited to th...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of serviceDoS attacks. blkrqmapuseriov function in the Linux kernel's block device implementation does not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a use-after-fre...

Improper Access Control

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 using the kfree function arbitrary kernel memory...

CVE-2018-20669: Improper Input Validation

An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in drivers/gpu/drm/i915/i915gemexecbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a...

Design/Logic Flaw

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...
