CVE-2019-3900 – Kernel: vhost_net: infinite loop while receiving packets leads to DoS
https://notcve.org/view.php?id=CVE-2019-3900
25 Apr 2019 — An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. Se encontró un problema de bucle infinito en el módulo del núcleo vhost_net en el kernel de Linux versiones anteriores a 5.1-rc6 inclusive, mientras ma... • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2019-11487 – kernel: Count overflow in FUSE request leading to use-after-free issues.
https://notcve.org/view.php?id=CVE-2019-11487
23 Apr 2019 — The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.

CVE-2019-3901 – kernel: perf_event_open() and execve() race in setuid programs allows a data leak
https://notcve.org/view.php?id=CVE-2019-3901
22 Apr 2019 — A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs. As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during ... • http://www.securityfocus.com/bid/89937 • CWE-667: Improper Locking •

11 Apr 2019 — The Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is enabled and ia32_aout is loaded, allows local users to bypass ASLR on setuid a.out programs (if any exist) because install_exec_creds() is called too late in load_aout_binary() in fs/binfmt_aout.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.
