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. A flaw was found in ethtool in the Linux kernel, where sysfs reader getting link settings can attempt to read the device state on a device that is not present, leading to a crash. • 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 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

https://notcve.org/view.php?id=CVE-2024-46677
In the Linux kernel, the following vulnerability has been resolved: gtp: fix a potential NULL pointer dereference When sockfd_lookup() fails, gtp_encap_enable_socket() returns a NULL pointer, but its callers only check for error pointers thus miss the NULL pointer case. Fix it by returning an error pointer with the error code carried from sockfd_lookup(). (I found this bug during code inspection.) • https://git.kernel.org/stable/c/1e3a3abd8b28cfda9d0d0167e50e0fe11bc372a9 https://git.kernel.org/stable/c/620fe9809752fae91b4190e897b81ed9976dfb39 https://git.kernel.org/stable/c/bdd99e5f0ad5fa727b16f2101fe880aa2bff2f8e https://git.kernel.org/stable/c/8bbb9e4e0e66a39282e582d0440724055404b38c https://git.kernel.org/stable/c/4643b91691e969b1b9ad54bf552d7a990cfa3b87 https://git.kernel.org/stable/c/e8b9930b0eb045d19e883c65ff9676fc89320c70 https://git.kernel.org/stable/c/28c67f0f84f889fe9f4cbda8354132b20dc9212d https://git.kernel.org/stable/c/612edd35f2a3910ab1f61c1f2338889d4 •
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. Found by Linux Verification Center (linuxtesting.org) with SVACE. • https://git.kernel.org/stable/c/dfccd0f580445d176acea174175b3e6518cc91f7 https://git.kernel.org/stable/c/c5e05237444f32f6cfe5d907603a232c77a08b31 https://git.kernel.org/stable/c/8ddaea033de051ed61b39f6b69ad54a411172b33 https://git.kernel.org/stable/c/7535db0624a2dede374c42040808ad9a9101d723 https://git.kernel.org/stable/c/7ecd3dd4f8eecd3309432156ccfe24768e009ec4 https://git.kernel.org/stable/c/56ad559cf6d87f250a8d203b555dfc3716afa946 https://git.kernel.org/stable/c/64513d0e546a1f19e390f7e5eba3872bfcbdacf5 https://git.kernel.org/stable/c/febccb39255f9df35527b88c953b2e0de •

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-2024-46674
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 •
