Summary
Important: kernel security, bug fix, and enhancement update
Details

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

Security Fix(es):

  • kernel: use after free in eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

  • kernel: SCSI target (LIO) write to any block on ILO backstore (CVE-2020-28374)

  • kernel: Use after free via PI futex state (CVE-2021-3347)

  • kernel: race conditions caused by wrong locking in net/vmw_vsock/af_vsock.c (CVE-2021-26708)

  • kernel: out-of-bounds read in libiscsi module (CVE-2021-27364)

  • kernel: heap buffer overflow in the iSCSI subsystem (CVE-2021-27365)

  • Kernel: KVM: host stack overflow due to lazy update IOAPIC (CVE-2020-27152)

  • kernel: iscsi: unrestricted access to sessions and handles (CVE-2021-27363)
