In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2 https://github.com/torvalds/linux/commit/4a625ceee8a0ab0273534cb6b432ce6b331db5ee • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2023-0461 – Use-after-free vulnerability in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-0461
There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c A use-after-free flaw was found in the Linux kernel’s TLS protocol functionality in how a user installs a tls context (struct tls_context) on a connected TCP socket. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2c02d41d71f90a5168391b6a5f2954112ba2307c https://kernel.dance/#2c02d41d71f90a5168391b6a5f2954112ba2307c https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://access.redhat.com/security/cve/CVE-2023-0461 https://bugzilla.redhat.com/show_bug.cgi?id=2176192 • CWE-416: Use After Free •
