https://notcve.org/view.php?id=CVE-2024-46829
In the Linux kernel, the following vulnerability has been resolved: rtmutex: Drop rt_mutex::wait_lock before scheduling rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the good case it returns with the lock held and in the deadlock case it emits a warning and goes into an endless scheduling loop with the lock held, which triggers the 'scheduling in atomic' warning. Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning and dropping into the schedule for ever loop. [ tglx: Moved unlock before the WARN(), removed the pointless comment, massaged changelog, added Fixes tag ] • https://git.kernel.org/stable/c/3d5c9340d1949733eb37616abd15db36aef9a57c https://git.kernel.org/stable/c/95f9aded9436aa3ce714aeff3f45fcc1431df7d2 https://git.kernel.org/stable/c/ea018da95368adfb700689bd9842714f7c3db665 https://git.kernel.org/stable/c/1201613a70dd34bd347ba2970919b3f1d5fbfb4a https://git.kernel.org/stable/c/a2e64fcdc83c645813f7b93e4df291841ba7c625 https://git.kernel.org/stable/c/fb52f40e085ef4074f1335672cd62c1f832af13b https://git.kernel.org/stable/c/2b1f3807ed9cafb59c956ce76a05d25e67103f2e https://git.kernel.org/stable/c/432efdbe7da5ecfcbc0c2180cfdbab144 •

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. • 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(). • https://git.kernel.org/stable/c/415f3634d53c7fb4cf07d2f5a0be7f2e15e6da33 https://git.kernel.org/stable/c/3cca098c91391b3fa48142bfda57048b985c87f6 https://git.kernel.org/stable/c/9215152677d4b321801a92b06f6d5248b2b4465f •

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://git.kernel.org/stable/c/d1207f07decc66546a7fa463d2f335a856c986ef https://git.kernel.org/stable/c/92e9bac18124682c4b99ede9ee3bcdd68f121e92 •

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. • https://git.kernel.org/stable/c/f57769ff6fa7f97f1296965f20e8a2bb3ee9fd0f https://git.kernel.org/stable/c/4c3b21204abb4fa3ab310fbbb5cf7f0e85f3a1bc https://git.kernel.org/stable/c/945be49f4e832a9184c313fdf8917475438a795b https://git.kernel.org/stable/c/40cae0df42e5e7f7a1c0f32deed9c4027c1ba94e https://git.kernel.org/stable/c/62ca6d3a905b4c40cd942f3cc645a6718f8bc7e7 https://git.kernel.org/stable/c/bc7fbb37e3d2df59336eadbd6a56be632e3c7df7 https://git.kernel.org/stable/c/2488444274c70038eb6b686cba5f1ce48ebb9cdd •
