https://notcve.org/view.php?id=CVE-2024-36244
In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: extend minimum interval restriction to entire cycle too It is possible for syzbot to side-step the restriction imposed by the blamed commit in the Fixes: tag, because the taprio UAPI permits a cycle-time different from (and potentially shorter than) the sum of entry intervals. We need one more restriction, which is that the cycle time itself must be larger than N * ETH_ZLEN bit times, where N is the number of schedule entries. This restriction needs to apply regardless of whether the cycle time came from the user or was the implicit, auto-calculated value, so we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)" branch. This way covers both conditions and scenarios. Add a selftest which illustrates the issue triggered by syzbot. • https://git.kernel.org/stable/c/b5b73b26b3ca34574124ed7ae9c5ba8391a7f176 https://git.kernel.org/stable/c/83bd58952b2b8543d8c48d1453975ab47a0a7504 https://git.kernel.org/stable/c/817ff50796c5e364c879596509f83fcba194bb6f https://git.kernel.org/stable/c/b939d1e04a90248b4cdf417b0969c270ceb992b2 https://git.kernel.org/stable/c/91f249b01fe490fce11fbb4307952ca8cce78724 https://git.kernel.org/stable/c/fb66df20a7201e60f2b13d7f95d031b31a8831d3 https://access.redhat.com/security/cve/CVE-2024-36244 https://bugzilla.redhat.com/show_bug.cgi?id=2293654 • CWE-20: Improper Input Validation •

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') •
