Vulnerability from certfr_avis - Published: 2023-05-19 - Updated: 2023-05-19
De multiples vulnérabilités ont été découvertes dans le noyau Linux d'Ubuntu. Elles permettent à un attaquant de provoquer une atteinte à la confidentialité des données, une exécution de code arbitraire à distance, une atteinte à l'intégrité des données, un déni de service et un contournement de la politique de sécurité.
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

Title
Spectre V1 Gadget in do_prlimit in the Linux Kernel
Summary
A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11

Title
Copy_from_user Spectre-V1 Gadget in Linux Kernel
Summary
Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47

CVE-2023-1078 (GCVE-0-2023-1078)
Vulnerability from cvelistv5 – Published: 2023-03-27 00:00 – Updated: 2025-05-05 16:07
VLAI
EPSS
Summary
A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info` actually points to something else that is potentially controlled by local user. It is known how to trigger this, which causes an out of bounds access, and a lock corruption.
