The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2854 advisory.
The kernel-alt packages provide the Linux kernel version 4.x.
Security Fix(es):
* kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)
* Kernel: ppc: kvm: conflicting use of HSTATE_HOST_R1 to store r1 state leads to host stack corruption (CVE-2020-8834)
* Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario (CVE-2020-12888)
* kernel: use after free due to race condition in the video driver leads to local privilege escalation (CVE-2019-9458)
* kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)
* kernel: use-after-free in drivers/bluetooth/hci_ldisc.c (CVE-2019-15917)
* kernel: memory leak in ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c (CVE-2019-18808)
* kernel: use-after-free in __ext4_expand_extra_isize and ext4_xattr_set_entry related to fs/ext4/inode.c and fs/ext4/super.c (CVE-2019-19767)
* kernel: an out-of-bounds write via crafted keycode table (CVE-2019-20636)
* kernel: use-after-free read in napi_gro_frags() in the Linux kernel (CVE-2020-10720)
* kernel: out-of-bounds write in mpol_parse_str function in mm/mempolicy.c (CVE-2020-11565)
* kernel: A memory leak in the crypto_report() function in crypto/crypto_user_base.c allows for a DoS (CVE-2019-19062)
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.
Bug Fix(es):
* XFS: Metadata corruption detected at xfs_attr3_leaf_read_verify [rhel-alt-7.6.z] (BZ#1830836)
