https://notcve.org/view.php?id=CVE-2024-46679
In the Linux kernel, the following vulnerability has been resolved: ethtool: check device is present when getting link settings A sysfs reader can race with a device reset or removal, attempting to read device state when the device is not actually present. eg: [exception RIP: qed_get_current_link+17] #8 [ffffb9e4f2907c48] qede_get_link_ksettings at ffffffffc07a994a [qede] #9 [ffffb9e4f2907cd8] __rh_call_get_link_ksettings at ffffffff992b01a3 #10 [ffffb9e4f2907d38] __ethtool_get_link_ksettings at ffffffff992b04e4 #11 [ffffb9e4f2907d90] duplex_show at ffffffff99260300 #12 [ffffb9e4f2907e38] dev_attr_show at ffffffff9905a01c #13 [ffffb9e4f2907e50] sysfs_kf_seq_show at ffffffff98e0145b #14 [ffffb9e4f2907e68] seq_read at ffffffff98d902e3 #15 [ffffb9e4f2907ec8] vfs_read at ffffffff98d657d1 #16 [ffffb9e4f2907f00] ksys_read at ffffffff98d65c3f #17 [ffffb9e4f2907f38] do_syscall_64 at ffffffff98a052fb crash> struct net_device.state ffff9a9d21336000 state = 5, state 5 is __LINK_STATE_START (0b1) and __LINK_STATE_NOCARRIER (0b100). The device is not present, note lack of __LINK_STATE_PRESENT (0b10). This is the same sort of panic as observed in commit 4224cfd7fb65 ("net-sysfs: add check for netdevice being present to speed_show"). There are many other callers of __ethtool_get_link_ksettings() which don't have a device presence check. Move this check into ethtool to protect all callers. • https://git.kernel.org/stable/c/d519e17e2d01a0ee9abe083019532061b4438065 https://git.kernel.org/stable/c/ec7b4f7f644018ac293cb1b02528a40a32917e62 https://git.kernel.org/stable/c/842a40c7273ba1c1cb30dda50405b328de1d860e https://git.kernel.org/stable/c/7a8d98b6d6484d3ad358510366022da080c37cbc https://git.kernel.org/stable/c/9bba5955eed160102114d4cc00c3d399be9bdae4 https://git.kernel.org/stable/c/94ab317024ba373d37340893d1c0358638935fbb https://git.kernel.org/stable/c/1d6d9b5b1b95bfeccb84386a51b7e6c510ec13b2 https://git.kernel.org/stable/c/a699781c79ecf6cfe67fb00a0331b4088 •
CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-46676 – nfc: pn533: Add poll mod list filling check
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.

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://git.kernel.org/stable/c/eca3f543f817da87c00d1a5697b473efb548204f https://git.kernel.org/stable/c/d2afc2bffec77316b90d530b07695e3f534df914 https://git.kernel.org/stable/c/b72da4d89b97da71e056cc4d1429b2bc426a9c2f https://git.kernel.org/stable/c/111277b881def3153335acfe0d1f43e6cd83ac93 https://git.kernel.org/stable/c/2189fd13c577d7881f94affc09c950a795064c4b https://git.kernel.org/stable/c/7bb11a75dd4d3612378b90e2a4aa49bdccea28ab https://git.kernel.org/stable/c/e23f6ad8d110bf632f7471482e10b43dc174fb72 https://git.kernel.org/stable/c/14e497183df28c006603cc67fd3797a53 •

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. • https://git.kernel.org/stable/c/8e0c5ebde82b08f6d996e11983890fc4cc085fab https://git.kernel.org/stable/c/d237c7d06ffddcdb5d36948c527dc01284388218 https://git.kernel.org/stable/c/564e1986b00c5f05d75342f8407f75f0a17b94df https://git.kernel.org/stable/c/9e96dea7eff6f2bbcd0b42a098012fc66af9eb69 https://git.kernel.org/stable/c/85449b28ff6a89c4513115e43ddcad949b5890c9 https://git.kernel.org/stable/c/60962c3d8e18e5d8dfa16df788974dd7f35bd87a https://git.kernel.org/stable/c/8a3995a3ffeca280a961b59f5c99843d81b15929 https://git.kernel.org/stable/c/4b540ec7c0045c2d01c4e479f34bbc8f1 •
