    3. Description:
    
    The kernel-alt packages provide the Linux kernel version 4.x.
    
    Security Fix(es):
    
    * Kernel: speculative bounds check bypass store (CVE-2018-3693)

    (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)
