The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (CVE-2017-18595)

  • kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c (CVE-2019-19768)

  • Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic (CVE-2020-10711)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
