概要
遠端 MiracleLinux 主機缺少一個或多個安全性更新。說明
遠端 MiracleLinux 7 主機已安裝受到多個弱點影響的套件如 AXSA:2024-8903:32 公告中所提及。* mediadvb-core修正 dvb_net 中因爭用情形而導致的釋放後使用 {CVE-2022-45886}
* mediadvb-core修正 dvb_ca_en50221 中的爭用情形造成的釋放後使用 {CVE-2022-45919}
* 連結修正 bond_option_arp_ip_targets_set() 中的超出邊界讀取 {CVE-2024-39487}
* net修正 __dst_negative_advice() 爭用 {CVE-2024-36971} CVE
CVE-2022-45886 在到 6.0.9為止的 Linux 核心中發現一個問題。 drivers/media/dvb-core/dvb_net.c 中有一個 .disconnect 與 dvb_device_open 爭用情形會導致釋放後使用。
CVE-2022-45919 在到 6.0.10為止的 Linux 核心中發現一個問題。在 drivers/media/dvb-core/dvb_ca_en50221.c 中，由於缺少 wait_event，如果打開後斷開連接，可能會發生釋放後使用。
CVE-2024-36971 在 Linux 核心中下列弱點已解決 net: fix __dst_negative_advice() race
__dst_negative_advice() does not enforce proper RCU rules when sk->dst_cache must be cleared, leading to possible UAF. RCU rules are that we must first clear sk->sk_dst_cache, then call dst_release(old_dst).
Note that sk_dst_reset(sk) is implementing this protocol correctly, while __dst_negative_advice() uses the wrong order. Given that ip6_negative_advice() has special logic against RTF_CACHE, this means each of the three ->negative_advice() existing methods must perform the sk_dst_reset() themselves. Note the check against NULL dst is centralized in __dst_negative_advice(), there is no need to duplicate it in various callbacks. Many thanks to Clement Lecigne for tracking this issue. This old bug became visible after the blamed commit, using UDP sockets.
CVE-2024-39487 In the Linux kernel, the following vulnerability has been resolved: bonding: Fix out-of-bounds read in bond_option_arp_ip_targets_set() In function bond_option_arp_ip_targets_set(), if newval->string is an empty string, newval->string+1 will point to the byte after the string, causing an out-of-bound read.
