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

CVE-2022-1462 (GCVE-0-2022-1462)
Vulnerability from cvelistv5 – Published: 2022-05-31 00:00 – Updated: 2024-08-03 00:03
VLAI
EPSS
Summary
An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.
Severity
No CVSS data available.

Summary
In the linux kernel, if IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents setting "ima_appraise=log" from the boot param when Secure Boot is enabled, but this does not cover cases where lockdown is used without Secure Boot. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity, Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
