03 Jul 2018 — An issue was discovered in fs/f2fs/inode.c in the Linux kernel through 4.17.3. A denial of service (slab out-of-bounds read and BUG) can occur for a modified f2fs filesystem image in which FI_EXTRA_ATTR is set in an inode.

02 Jul 2018 — An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer ove... • https://bugzilla.kernel.org/show_bug.cgi?id=200189 • CWE-190: Integer Overflow or Wraparound •

02 Jul 2018 — The alarm_timer_nsleep function in kernel/time/alarmtimer.c in the Linux kernel through 4.17.3 has an integer overflow via a large relative timeout because ktime_add_safe is not used. La función alarm_timer_nsleep en kernel/time/alarmtimer.c en el kernel de Linux hasta la versión 4.17.3 tiene un desbordamiento de enteros a través de un tiempo de espera relativo grande porque no se utiliza ktime_add_safe.

27 Jun 2018 — In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of service attacks due to lack of checking of CPL. En arch/x86/kvm/vmx.c en el kernel de Linux en versiones anteriores a la 4.17.2, cuando se emplea la virtualización anidada, los atacantes locales podrían hacer que los invitados L1 KVM realizasen un VMEXIT, permitiendo escalados de privilegios y ataques de den... • https://www.exploit-db.com/exploits/44944 •

22 Jun 2018 — An issue was discovered in the Linux kernel through 4.17.2. vbg_misc_device_ioctl() in drivers/virt/vboxguest/vboxguest_linux.c reads the same user data twice with copy_from_user. The header part of the user data is double-fetched, and a malicious user thread can tamper with the critical variables (hdr.size_in and hdr.size_out) in the header between the two fetches because of a race condition, leading to severe kernel errors, such as buffer over-accesses. This bug can cause a local denial of service and inf... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd23a7269834dc7c1f93e83535d16ebc44b75eba • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

21 Jun 2018 — An issue was discovered in the Linux kernel through 4.17.2. Since the page allocator does not yield CPU resources to the owner of the oom_lock mutex, a local unprivileged user can trivially lock up the system forever by wasting CPU resources from the page allocator (e.g., via concurrent page fault events) when the global OOM killer is invoked. NOTE: the software maintainer has not accepted certain proposed patches, in part because of a viewpoint that "the underlying problem is non-trivial to handle. ** EN D... • https://patchwork.kernel.org/patch/10395909 • CWE-399: Resource Management Errors •

12 Jun 2018 — In net/socket.c in the Linux kernel through 4.17.1, there is a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions. fchownat does not increment the file descriptor reference count, which allows close to set the socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash.
