https://notcve.org/view.php?id=CVE-2024-33619
In the Linux kernel, the following vulnerability has been resolved: efi: libstub: only free priv.runtime_map when allocated priv.runtime_map is only allocated when efi_novamap is not set. Otherwise, it is an uninitialized value. In the error path, it is freed unconditionally. Avoid passing an uninitialized value to free_pool. Free priv.runtime_map only when it was allocated. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc. • https://git.kernel.org/stable/c/f80d26043af91ceb5036c478101c015edb9e7630 https://git.kernel.org/stable/c/b8938d6f570f010a1dcdbfed3e5b5d3258c2a908 https://git.kernel.org/stable/c/9dce01f386c9ce6990c0a83fa14b1c95330b037e https://git.kernel.org/stable/c/6ca67a5fe1c606d1fbe24c30a9fc0bdc43a18554 https://git.kernel.org/stable/c/4b2543f7e1e6b91cfc8dd1696e3cdf01c3ac8974 •
CVSS: 5.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-31076 – genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline
https://notcve.org/view.php?id=CVE-2024-31076
In the Linux kernel, the following vulnerability has been resolved: genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline The absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness of interrupt affinity reconfiguration via procfs. Instead, the change is deferred until the next instance of the interrupt being triggered on the original CPU. When the interrupt next triggers on the original CPU, the new affinity is enforced within __irq_move_irq(). A vector is allocated from the new CPU, but the old vector on the original CPU remains and is not immediately reclaimed. Instead, apicd->move_in_progress is flagged, and the reclaiming process is delayed until the next trigger of the interrupt on the new CPU. Upon the subsequent triggering of the interrupt on the new CPU, irq_complete_move() adds a task to the old CPU's vector_cleanup list if it remains online. Subsequently, the timer on the old CPU iterates over its vector_cleanup list, reclaiming old vectors. However, a rare scenario arises if the old CPU is outgoing before the interrupt triggers again on the new CPU. In that case irq_force_complete_move() is not invoked on the outgoing CPU to reclaim the old apicd->prev_vector because the interrupt isn't currently affine to the outgoing CPU, and irq_needs_fixup() returns false. • https://git.kernel.org/stable/c/f0383c24b4855f6a4b5a358c7b2d2c16e0437e9b https://git.kernel.org/stable/c/a40209d355afe4ed6d533507838c9e5cd70a76d8 https://git.kernel.org/stable/c/f5f4675960609d8c5ee95f027fbf6ce380f98372 https://git.kernel.org/stable/c/6752dfcfff3ac3e16625ebd3f0ad9630900e7e76 https://git.kernel.org/stable/c/9eeda3e0071a329af1eba15f4e57dc39576bb420 https://git.kernel.org/stable/c/e9c96d01d520498b169ce734a8ad1142bef86a30 https://git.kernel.org/stable/c/59f86a2908380d09cdc726461c0fbb8d8579c99f https://git.kernel.org/stable/c/ebfb16fc057a016abb46a9720a54abf0d • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •
