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-2024-26982 – Squashfs: check the inode number is not the invalid value of zero
https://notcve.org/view.php?id=CVE-2024-26982
01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: Squashfs: check the inode number is not the invalid value of zero Syskiller has produced an out of bounds access in fill_meta_index(). That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked. The reason this causes the out of bounds access is due to following sequence of events: 1. Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a me... • https://git.kernel.org/stable/c/be383effaee3d89034f0828038f95065b518772e • CWE-125: Out-of-bounds Read •

CVE-2024-26976 – KVM: Always flush async #PF workqueue when vCPU is being destroyed

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: KVM: Always flush async #PF workqueue when vCPU is being destroyed Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure that none of its workqueue callbacks is running when the last reference to the KVM _module_ is put. Gifting a reference to the associated VM prevents the workqueue callback from dereferencing freed vCPU/VM memory, bu... • https://git.kernel.org/stable/c/af585b921e5d1e919947c4b1164b59507fe7cd7b • CWE-400: Uncontrolled Resource Consumption •
CVE-2024-26962 – dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape

However, for dm-raid, in following cases reshape will never make progress hence IO will hang: 1) the array is read-only; 2) MD_RECOVERY_WAIT is set; 3) MD_RECOVERY_FROZEN is set; After commit c467e97f079f ("md/raid6: use valid sector value... • https://git.kernel.org/stable/c/5943a34bf6bab5801e08a55f63e1b8d5bc90dae1 •

This resolves a kernel BUG reported by syzbot. Since there are two flaws involved, I've made each one a separate patch. The first patch alone resolves the syzbot-reported bug, but I think both fixes should be sent to stable, so I've tagged them as such.
