Out-Of-Bounds Read

Linux kernel is vulnerable to out-of-bounds read vulnerability. The vulnerability exists in the adjustscalarminmaxvals function in kernel/bpf/verifier.c due to faulty computation of numeric bounds in the BPF verifier as it mishandles 32-bit right shifts causing an out-of-bounds memory access...

Denial Of Service (DoS)

The kernel-rt 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 PI futexes. A local, unprivileged user could use this flaw to escalate their privileges on...

CVE-2017-18367

CVE-2017-18367 affects libseccomp-golang 0.9.0 and earlier. The root cause is that the BPFs generated by libseccomp-golang OR multiple syscall-argument checks instead of ANDing them, enabling a process under a restrictive seccomp filter that specifies multiple arguments to bypass the intended acc...

CVE-2017-18367

libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument...
