Amazon Linux 2 : kernel (ALASKERNEL-5.10-2022-018)

2022-07-22T00:00:00

Description

The version of kernel installed on the remote host is prior to 5.10.130-118.517. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-018 advisory. - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. (CVE-2022-2318) - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740). Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742) - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further processing to nevertheless be freed. (CVE-2022-33743) - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages. (CVE-2022-33744) - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. (CVE-2022-34918) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

(CVE-2022-2318)\n\n - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text\n explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device\n frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).\n Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to\n unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend\n (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data\n Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further\n processing to nevertheless be freed. (CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree\n to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the\n related lock held, resulting in a small race window, which can be used by unprivileged guests via PV\n devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)\n of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory\n pages. (CVE-2022-33744)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init\n (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different\n vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an\n unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data\n in net/netfilter/nf_tables_api.c. (CVE-2022-34918)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

Xen Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740, XSA-403). Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742, XSA-403). Xen network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further processing to nevertheless be freed (CVE-2022-33743, XSA-405). Xen Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These in consistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests memory pages (CVE-2022-33744, XSA-406). An issue was discovered in the Linux kernel through 5.18.9.

(CVE-2021-33655)\n\n - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that\n allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)\n\n - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text\n explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device\n frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).\n Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to\n unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend\n (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data\n Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further\n processing to nevertheless be freed. (CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree\n to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the\n related lock held, resulting in a small race window, which can be used by unprivileged guests via PV\n devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)\n of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory\n pages. (CVE-2022-33744)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init\n (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different\n vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an\n unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data\n in net/netfilter/nf_tables_api.c.

These inconsistencies can lead to Denial of Service (DoS)\n of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory\n pages.

(CVE-2021-28689)\n\n - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text\n explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device\n frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).\n Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to\n unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend\n (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - P2M pool freeing may take excessively long The P2M pool backing second level address translation for\n guests may be of significant size. Therefore its freeing may take more time than is reasonable without\n intermediate preemption checks. Such checking for the need to preempt was so far missing. (CVE-2022-33746)\n\n - lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was\n inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a\n result two cooperating guests granting each other transitive grants can cause locks to be acquired nested\n within one another, but in respectively opposite order. With suitable timing between the involved grant\n copy operations this may result in the locking up of a CPU.

Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages.
