https://notcve.org/view.php?id=CVE-2024-46676
In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: Add poll mod list filling check In case of im_protocols value is 1 and tm_protocols value is 0 this combination successfully passes the check 'if (!im_protocols && !tm_protocols)' in the nfc_start_poll(). But then after pn533_poll_create_mod_list() call in pn533_start_poll() poll mod list will remain empty and dev->poll_mod_count will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. But these protocol values actually come from userspace via Netlink interface (NFC_CMD_START_POLL operation). So a broken or malicious program may pass a message containing a "bad" combination of protocol parameter values so that dev->poll_mod_count is not incremented inside pn533_poll_create_mod_list(), thus leading to division by zero. Call trace looks like: nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll() Add poll mod list filling check.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-46675 – usb: dwc3: core: Prevent USB core invalid event buffer address access
https://notcve.org/view.php?id=CVE-2024-46675
In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: core: Prevent USB core invalid event buffer address access This commit addresses an issue where the USB core could access an invalid event buffer address during runtime suspend, potentially causing SMMU faults and other memory issues in Exynos platforms. The problem arises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address. To prevent this hardware quirk on Exynos platforms, this commit ensures that the event buffer address is not cleared by software when the USB core is active during runtime suspend by checking its status before clearing the buffer address.

https://notcve.org/view.php?id=CVE-2024-46674
In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: st: fix probed platform device ref count on probe error path The probe function never performs any paltform device allocation, thus error path "undo_platform_dev_alloc" is entirely bogus. It drops the reference count from the platform device being probed. If error path is triggered, this will lead to unbalanced device reference counts and premature release of device resources, thus possible use-after-free when releasing remaining devm-managed resources. • https://git.kernel.org/stable/c/f83fca0707c66e36f14efef7f68702cb12de70b7 https://git.kernel.org/stable/c/b0979a885b9d4df2a25b88e9d444ccaa5f9f495c https://git.kernel.org/stable/c/f3498650df0805c75b4e1c94d07423c46cbf4ce1 https://git.kernel.org/stable/c/6aee4c5635d81f4809c3b9f0c198a65adfbb2ada https://git.kernel.org/stable/c/060f41243ad7f6f5249fa7290dda0c01f723d12d https://git.kernel.org/stable/c/4c6735299540f3c82a5033d35be76a5c42e0fb18 https://git.kernel.org/stable/c/e1e5e8ea2731150d5ba7c707f9e02fafebcfeb49 https://git.kernel.org/stable/c/1de989668708ce5875efc9d669d227212 •

https://notcve.org/view.php?id=CVE-2024-46673
In the Linux kernel, the following vulnerability has been resolved: scsi: aacraid: Fix double-free on probe failure aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer, all of which eventually call down to aac_init_adapter(). If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member. After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.
