Updated kernel packages fix security vulnerabilities

This kernel update is based on the upstream 4.14.78 and fixes at least the following security issues: An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the...

Linux kernel out-of-bounds access vulnerability (CNVD-2018-26908)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the BPF verifier in the Linux kernel, which arises from the program failing to properly compute numeric bounds. An attacker could...

CVE-2018-18445

In the Linux kernel 4.14.x, 4.15.x, 4.16.x, 4.17.x, and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjustscalarminmaxvals in kernel/bpf/verifier.c mishandles 32-bit right shifts...

CVE-2018-18445

CVE-2018-18445 affects the Linux kernel in 4.14.x–4.18.x; prior to 4.18.13, the BPF verifier’s adjust_scalar_min_max_vals mishandles 32-bit right shifts, enabling out-of-bounds memory accesses. Several advisories confirm the issue and reference the fix in 4.18.13 (and backported patches for earli...
