RHSA-2020:3041: Important: kernel security and bug fix update
First published: Tue Jul 21 2020(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>Security Fix(es):<br><li> kernel: kernel: DAX hugepages not considered during mremap (CVE-2020-10757)</li> <li> kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug allows an attacker to turn off the SSBD protection. (CVE-2020-10766)</li> <li> kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available. (CVE-2020-10767)</li> <li> kernel: Indirect branch speculation can be enabled after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command. (CVE-2020-10768)</li> <li> kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in drivers/net/wireless/marvell/mwifiex/scan.c (CVE-2020-12653)</li> <li> kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in drivers/net/wireless/marvell/mwifiex/wmm.c (CVE-2020-12654)</li> <li> Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario (CVE-2020-12888)</li> 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.<br>Bug Fix(es):<br><li> [ESXi][RHEL8.1.0] scsi driver SG list incompatibility (vmw_pvscsi) (BZ#1839359)</li>
