kernel: Out of bound access in hugetlb_mcopy_atomic_pte function in mm/hugetlb.c

A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13.12. A lack of size check could cause a denial of service (BUG).

kernel: Improper error handling of VM_SHARED hugetlbfs mapping in mm/hugetlb.c

A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service (BUG).

kernel: Use-after-free in userfaultfd_event_wait_completion function in userfaultfd.c

A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is related to the handling of fork failure when dealing with event messages. Failure to fork correctly can lead to a situation where a fork event will be removed from an already freed list of events with userfaultfd_ctx_put().

kernel: security: The built-in keyrings for security tokens can be joined as a session and then modified by the root user

It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

Cross-site scripting (XSS) vulnerability in Sophos PureMessage for UNIX before 6.3.2 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

chromium-browser: various fixes from internal audits

browser/extensions/api/dial/dial_registry.cc in Google Chrome before 54.0.2840.98 on macOS, before 54.0.2840.99 on Windows, and before 54.0.2840.100 on Linux neglects to copy a device ID before an erase() call, which causes the erase operation to access data that that erase operation will destroy.

kernel: out of bounds write in ad5755_parse_dt in drivers/iio/dac/ad5755.c

An issue was discovered in drivers/iio/dac/ad5755.c in the Linux kernel before 4.8.6. There is an out of bounds write in the function ad5755_parse_dt.

kernel: use-after-free in functions arc_emac_tx and arc_emac_tx_clean in drivers/net/ethernet/arc/emac_main.c

An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use-after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.

kernel: use-after-free in fs/gfs2/rgrp.c

An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by the functions gfs2_clear_rgrpd and read_rindex_entry.

kernel: off by one in function cqspi_setup_flash() in drivers/mtd/spi-nor/cadence-quadspi.c

In the Linux kernel before 4.9.6, there is an off by one in the drivers/mtd/spi-nor/cadence-quadspi.c cqspi_setup_flash() function. There are CQSPI_MAX_CHIPSELECT elements in the ->f_pdata array so the ">" should be ">=" instead.
