https://notcve.org/view.php?id=CVE-2024-53074
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't leak a link on AP removal Release the link mapping resource in AP removal. This impacted devices that do not support the MLD API (9260 and down). On those devices, we couldn't start the AP again after the AP has been already started and stopped. • https://git.kernel.org/stable/c/a8b5d4809b503da668966a8187b9872e6c85291c https://git.kernel.org/stable/c/70ddf9ce1894c48dbbf10b0de51a95e4fb3dd376 https://git.kernel.org/stable/c/3ed092997a004d68a3a5b0eeb94e71b69839d0f7 •

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-53071 – drm/panthor: Be stricter about IO mapping flags
https://notcve.org/view.php?id=CVE-2024-53071
In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Be stricter about IO mapping flags The current panthor_device_mmap_io() implementation has two issues: 1. For mapping DRM_PANTHOR_USER_FLUSH_ID_MMIO_OFFSET, panthor_device_mmap_io() bails if VM_WRITE is set, but does not clear VM_MAYWRITE. That means userspace can use mprotect() to make the mapping writable later on. This is a classic Linux driver gotcha. I don't think this actually has any impact in practice: When the GPU is powered, writes to the FLUSH_ID seem to be ignored; and when the GPU is not powered, the dummy_latest_flush page provided by the driver is deliberately designed to not do any flushes, so the only thing writing to the dummy_latest_flush could achieve would be to make *more* flushes happen. 2. panthor_device_mmap_io() does not block MAP_PRIVATE mappings (which are mappings without the VM_SHARED flag). MAP_PRIVATE in combination with VM_MAYWRITE indicates that the VMA has copy-on-write semantics, which for VM_PFNMAP are semi-supported but fairly cursed. In particular, in such a mapping, the driver can only install PTEs during mmap() by calling remap_pfn_range() (because remap_pfn_range() wants to **store the physical address of the mapped physical memory into the vm_pgoff of the VMA**); installing PTEs later on with a fault handler (as panthor does) is not supported in private mappings, and so if you try to fault in such a mapping, vmf_insert_pfn_prot() splats when it hits a BUG() check. Fix it by clearing the VM_MAYWRITE flag (userspace writing to the FLUSH_ID doesn't make sense) and requiring VM_SHARED (copy-on-write semantics for the FLUSH_ID don't make sense). Reproducers for both scenarios are in the notes of my patch on the mailing list; I tested that these bugs exist on a Rock 5B machine. Note that I only compile-tested the patch, I haven't tested it; I don't have a working kernel build setup for the test machine yet. Please test it before applying it. • https://git.kernel.org/stable/c/5fe909cae118a757a77afb37174b99436a36d2e2 https://git.kernel.org/stable/c/2604afd65043e8f9d4be036cb1242adf6b5723cf https://git.kernel.org/stable/c/f432a1621f049bb207e78363d9d0e3c6fa2da5db •

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: fix fault at system suspend if device was already runtime suspended If the device was already runtime suspended then during system suspend we cannot access the device registers else it will crash. Also we cannot access any registers after dwc3_core_exit() on some platforms so move the dwc3_enable_susphy() call to the top. • https://git.kernel.org/stable/c/073530898ebf44a9418434e899cfa9ca86945333 https://git.kernel.org/stable/c/85ca88f93162acb94dbcb26d0ee2b145864d14a1 https://git.kernel.org/stable/c/4fad7370086797afe6471493e3a5f36add8c48a7 https://git.kernel.org/stable/c/a690a9e38e6ba819789074388de7cff06425ef5b https://git.kernel.org/stable/c/d9e65d461a9de037e7c9d584776d025cfce6d86d https://git.kernel.org/stable/c/562804b1561cc248cc37746a1c96c83cab1d7209 https://git.kernel.org/stable/c/4abc5ee334fe4aba50461c45fdaaa4c5e5c57789 https://git.kernel.org/stable/c/06b98197b69e2f2af9cb1991ee0b1c876 •
