RedHat: RHSA-2020-0174:01 Important: kernel-alt security and bug fix update
Summary
The kernel-alt packages provide the Linux kernel version 4.x.
Security Fix(es):
* Kernel: speculative bounds check bypass store (CVE-2018-3693)
* kernel: Use-after-free due to race condition in AF_PACKET implementation
(CVE-2018-18559)
* kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in
marvell/mwifiex/scan.c (CVE-2019-3846)
* kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL value
for a certain structure member, which leads to a use-after-free in
sockfs_setattr (CVE-2019-8912)
* kernel: Heap overflow in mwifiex_uap_parse_tail_ies function in
drivers/net/wireless/marvell/mwifiex/ie.c (CVE-2019-10126)
* kernel: Count overflow in FUSE request leading to use-after-free issues.
(CVE-2019-11487)
* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi
driver (CVE-2019-14816)
* kernel: buffer overflow in cfg80211_mgd_wext_giwessid in
net/wireless/wext-sme.c (CVE-2019-17133)
* kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi
Driver leading to DoS (CVE-2019-14814)
* kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell
WiFi driver leading to DoS (CVE-2019-14815)
* kernel: (powerpc) incomplete Spectre-RSB mitigation leads to information
exposure (CVE-2019-18660)
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):
* Kernel panic on job cleanup, related to SyS_getdents64 (BZ#1702057)
* Kernel modules generated incorrectly when system is localized to
non-English language (BZ#1705285)
* RHEL-Alt-7.6 - Fixup tlbie vs store ordering issue on POWER9 (BZ#1756270)
