https://notcve.org/view.php?id=CVE-2024-46826
In the Linux kernel, the following vulnerability has been resolved: ELF: fix kernel.randomize_va_space double read ELF loader uses "randomize_va_space" twice. It is sysctl and can change at any moment, so 2 loads could see 2 different values in theory with unpredictable consequences. Issue exactly one load for consistent value across one exec. Ubuntu Security Notice 7155-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. • https://git.kernel.org/stable/c/1f81d51141a234ad0a3874b4d185dc27a521cd27 https://git.kernel.org/stable/c/53f17409abf61f66b6f05aff795e938e5ba811d1 https://git.kernel.org/stable/c/1cf8cd80903073440b6ea055811d04edd24fe4f7 https://git.kernel.org/stable/c/2a97388a807b6ab5538aa8f8537b2463c6988bd2 https://access.redhat.com/security/cve/CVE-2024-46826 https://bugzilla.redhat.com/show_bug.cgi?id=2315178 • CWE-20: Improper Input Validation •

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check The lookup function iwl_mvm_rcu_fw_link_id_to_link_conf() is normally called with input from the firmware, so it should use IWL_FW_CHECK() instead of WARN_ON(). Ubuntu Security Notice 7156-1 - Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing.

https://notcve.org/view.php?id=CVE-2024-46823
In the Linux kernel, the following vulnerability has been resolved: kunit/overflow: Fix UB in overflow_allocation_test The 'device_name' array doesn't exist out of the 'overflow_allocation_test' function scope. However, it is being used as a driver name when calling 'kunit_driver_create' from 'kunit_device_register'. It produces the kernel panic with KASAN enabled. Since this variable is used in one place only, remove it and pass the device name into kunit_device_register directly as an ascii string.

https://notcve.org/view.php?id=CVE-2024-46822
In the Linux kernel, the following vulnerability has been resolved: arm64: acpi: Harden get_cpu_for_acpi_id() against missing CPU entry In a review discussion of the changes to support vCPU hotplug where a check was added on the GICC being enabled if was online, it was noted that there is need to map back to the cpu and use that to index into a cpumask. As such, a valid ID is needed. If an MPIDR check fails in acpi_map_gic_cpu_interface() it is possible for the entry in cpu_madt_gicc[cpu] == NULL. This function would then cause a NULL pointer dereference. Whilst a path to trigger this has not been established, harden this caller against the possibility.
