https://notcve.org/view.php?id=CVE-2024-26996
01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_ncm: Fix UAF ncm object at re-bind after usb ep transport error When ncm function is working and then stop usb0 interface for link down, eth_stop() is called. At this piont, accidentally if usb transport error should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled. After that, ncm_disable() is called to disable for ncm unbind but gether_disconnect() is never called since 'in_ep' is not enabled.

CVE-2024-26993 – fs: sysfs: Fix reference leak in sysfs_break_active_protection()

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: fs: sysfs: Fix reference leak in sysfs_break_active_protection() The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at t... • https://git.kernel.org/stable/c/2afc9166f79b8f6da5f347f48515215ceee4ae37 •
CVE-2024-26992 – KVM: x86/pmu: Disable support for adaptive PEBS
https://notcve.org/view.php?id=CVE-2024-26992
01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: KVM: x86/pmu: Disable support for adaptive PEBS Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak host kernel addresses to the guest. Bug #1 is that KVM doesn't account for the upper 32 bits of IA32_FIXED_CTR_CTRL when (re)programming fixed counters, e.g fixed_ctrl_field() drops... • https://git.kernel.org/stable/c/c59a1f106f5cd4843c097069ff1bb2ad72103a67 •
CVE-2024-26990 – KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status

Specifically, TDP MMU SPTEs must be write-protected when the TDP MMU is being used to run an L2 (i.e. L1 has disabled EPT) and PML is enabled.
