CVSS: 4.7EPSS: 0%CPEs: 11EXPL: 0CVE-2023-26545 – kernel: mpls: double free on sysctl allocation failure
https://notcve.org/view.php?id=CVE-2023-26545
In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device. A double-free flaw was found in the Linux kernel when the MPLS implementation handled sysctl allocation failures. This issue could allow a local user to cause a denial of service or possibly execute arbitrary code. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.13 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fda6c89fe3d9aca073495a664e1d5aea28cd4377 https://github.com/torvalds/linux/commit/fda6c89fe3d9aca073495a664e1d5aea28cd4377 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230316-0009 https://access.redhat.com/security/cve/CVE-2023-26545 • CWE-415: Double Free •
CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 3CVE-2023-0045 – Incorrect indirect branch prediction barrier in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-0045
The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to the prctl syscall. The patch that added the support for the conditional mitigation via prctl (ib_prctl_set) dates back to the kernel 4.9.176.
