Title:RHSA-2020:5437: kernel security and bug fix update (Important)
Description:The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385)

  • kernel: The flow_dissector feature allows device tracking (CVE-2019-18282)

  • kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned. (CVE-2020-10769)

  • kernel: buffer uses out of index in ext3/4 filesystem (CVE-2020-14314)

  • kernel: umask not applied on filesystem without ACL support (CVE-2020-24394)

  • kernel: TOCTOU mismatch in the NFS client code (CVE-2020-25212)

  • kernel: improper input validation in ppp_cp_parse_cr function leads to memory corruption and read overflow (CVE-2020-25643)
