Vulnerability from certfr_avis - Published: 2022-10-04 - Updated: 2022-10-04
De multiples vulnérabilités ont été corrigées dans le noyau Linux d'Ubuntu. Elles permettent à un attaquant de provoquer un déni de service à distance, une atteinte à la confidentialité des données, un contournement de la politique de sécurité et une exécution de code arbitraire.
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

CVE-2022-2639 (GCVE-0-2022-2639)
Vulnerability from cvelistv5 – Published: 2022-09-01 20:32 – Updated: 2024-08-03 00:46

EPSS
Summary
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.
Severity
No CVSS data available.

CVE-2022-3028 (GCVE-0-2022-3028)
Vulnerability from cvelistv5 – Published: 2022-08-31 00:00 – Updated: 2024-08-03 00:53
VLAI
EPSS
Summary
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.
Severity
No CVSS data available.

EPSS
Summary
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-2022-33744 (GCVE-0-2022-33744)
Vulnerability from cvelistv5 – Published: 2022-07-05 12:50 – Updated: 2024-08-03 08:09
VLAI
EPSS
Summary
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.
Severity
No CVSS data available.
