In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btbcm: Fix NULL deref in btbcm_get_board_name() devm_kstrdup() can return a NULL pointer on failure,but this returned value in btbcm_get_board_name() is not checked. Add NULL check in btbcm_get_board_name(), to handle kernel NULL pointer dereference error.
CVE-2024-57987 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: check for NULL in btrtl_setup_realtek() If insert an USB dongle which chip is not maintained in ic_id_table, it will hit the NULL point accessed. Add a null point check to avoid the Kernel Oops.
CVE-2024-57944 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-ads1298: Add NULL check in ads1298_init devm_kasprintf() can return a NULL pointer on failure. A check on the return value of such a call in ads1298_init() is missing. Add it.
CVE-2024-57934 1 Linux 1 Linux Kernel 2025-10-01 N/A 4.7 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: fgraph: Add READ_ONCE() when accessing fgraph_array[] In __ftrace_return_to_handler(), a loop iterates over the fgraph_array[] elements, which are fgraph_ops. The loop checks if an element is a fgraph_stub to prevent using a fgraph_stub afterward. However, if the compiler reloads fgraph_array[] after this check, it might race with an update to fgraph_array[] that introduces a fgraph_stub. This could result in the stub being processed, but the stub contains a null "func_hash" field, leading to a NULL pointer dereference. To ensure that the gops compared against the fgraph_stub matches the gops processed later, add a READ_ONCE(). A similar patch appears in commit 63a8dfb ("function_graph: Add READ_ONCE() when accessing fgraph_array[]").
CVE-2024-57933 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: gve: guard XSK operations on the existence of queues This patch predicates the enabling and disabling of XSK pools on the existence of queues. As it stands, if the interface is down, disabling or enabling XSK pools would result in a crash, as the RX queue pointer would be NULL. XSK pool registration will occur as part of the next interface up. Similarly, xsk_wakeup needs be guarded against queues disappearing while the function is executing, so a check against the GVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with the disabling of the bit and the synchronize_net() in gve_turndown.
CVE-2024-57927 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: nfs: Fix oops in nfs_netfs_init_request() when copying to cache When netfslib wants to copy some data that has just been read on behalf of nfs, it creates a new write request and calls nfs_netfs_init_request() to initialise it, but with a NULL file pointer. This causes nfs_file_open_context() to oops - however, we don't actually need the nfs context as we're only going to write to the cache. Fix this by just returning if we aren't given a file pointer and emit a warning if the request was for something other than copy-to-cache. Further, fix nfs_netfs_free_request() so that it doesn't try to free the context if the pointer is NULL.
CVE-2024-57925 1 Linux 1 Linux Kernel 2025-10-01 N/A 7.1 HIGH
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix a missing return value check bug In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct() fails to allocate a node, it returns a NULL pointer to the in_work pointer. This can lead to an illegal memory write of in_work->response_buf when allocate_interim_rsp_buf() attempts to perform a kzalloc() on it. To address this issue, incorporating a check for the return value of ksmbd_alloc_work_struct() ensures that the function returns immediately upon allocation failure, thereby preventing the aforementioned illegal memory access.
CVE-2024-57914 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpci: fix NULL pointer issue on shared irq case The tcpci_irq() may meet below NULL pointer dereference issue: [ 2.641851] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010 [ 2.641951] status 0x1, 0x37f [ 2.650659] Mem abort info: [ 2.656490] ESR = 0x0000000096000004 [ 2.660230] EC = 0x25: DABT (current EL), IL = 32 bits [ 2.665532] SET = 0, FnV = 0 [ 2.668579] EA = 0, S1PTW = 0 [ 2.671715] FSC = 0x04: level 0 translation fault [ 2.676584] Data abort info: [ 2.679459] ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 [ 2.684936] CM = 0, WnR = 0, TnD = 0, TagAccess = 0 [ 2.689980] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [ 2.695284] [0000000000000010] user address but active_mm is swapper [ 2.701632] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP [ 2.707883] Modules linked in: [ 2.710936] CPU: 1 UID: 0 PID: 87 Comm: irq/111-2-0051 Not tainted 6.12.0-rc6-06316-g7f63786ad3d1-dirty #4 [ 2.720570] Hardware name: NXP i.MX93 11X11 EVK board (DT) [ 2.726040] pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 2.732989] pc : tcpci_irq+0x38/0x318 [ 2.736647] lr : _tcpci_irq+0x14/0x20 [ 2.740295] sp : ffff80008324bd30 [ 2.743597] x29: ffff80008324bd70 x28: ffff800080107894 x27: ffff800082198f70 [ 2.750721] x26: ffff0000050e6680 x25: ffff000004d172ac x24: ffff0000050f0000 [ 2.757845] x23: ffff000004d17200 x22: 0000000000000001 x21: ffff0000050f0000 [ 2.764969] x20: ffff000004d17200 x19: 0000000000000000 x18: 0000000000000001 [ 2.772093] x17: 0000000000000000 x16: ffff80008183d8a0 x15: ffff00007fbab040 [ 2.779217] x14: ffff00007fb918c0 x13: 0000000000000000 x12: 000000000000017a [ 2.786341] x11: 0000000000000001 x10: 0000000000000a90 x9 : ffff80008324bd00 [ 2.793465] x8 : ffff0000050f0af0 x7 : ffff00007fbaa840 x6 : 0000000000000031 [ 2.800589] x5 : 000000000000017a x4 : 0000000000000002 x3 : 0000000000000002 [ 2.807713] x2 : ffff80008324bd3a x1 : 0000000000000010 x0 : 0000000000000000 [ 2.814838] Call trace: [ 2.817273] tcpci_irq+0x38/0x318 [ 2.820583] _tcpci_irq+0x14/0x20 [ 2.823885] irq_thread_fn+0x2c/0xa8 [ 2.827456] irq_thread+0x16c/0x2f4 [ 2.830940] kthread+0x110/0x114 [ 2.834164] ret_from_fork+0x10/0x20 [ 2.837738] Code: f9426420 f9001fe0 d2800000 52800201 (f9400a60) This may happen on shared irq case. Such as two Type-C ports share one irq. After the first port finished tcpci_register_port(), it may trigger interrupt. However, if the interrupt comes by chance the 2nd port finishes devm_request_threaded_irq(), the 2nd port interrupt handler will run at first. Then the above issue happens due to tcpci is still a NULL pointer in tcpci_irq() when dereference to regmap. devm_request_threaded_irq() <-- port1 irq comes disable_irq(client->irq); tcpci_register_port() This will restore the logic to the state before commit (77e85107a771 "usb: typec: tcpci: support edge irq"). However, moving tcpci_register_port() earlier creates a problem when use edge irq because tcpci_init() will be called before devm_request_threaded_irq(). The tcpci_init() writes the ALERT_MASK to the hardware to tell it to start generating interrupts but we're not ready to deal with them yet, then the ALERT events may be missed and ALERT line will not recover to high level forever. To avoid the issue, this will also set ALERT_MASK register after devm_request_threaded_irq() return.
CVE-2024-57881 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: mm/page_alloc: don't call pfn_to_page() on possibly non-existent PFN in split_large_buddy() In split_large_buddy(), we might call pfn_to_page() on a PFN that might not exist. In corner cases, such as when freeing the highest pageblock in the last memory section, this could result with CONFIG_SPARSEMEM && !CONFIG_SPARSEMEM_EXTREME in __pfn_to_section() returning NULL and and __section_mem_map_addr() dereferencing that NULL pointer. Let's fix it, and avoid doing a pfn_to_page() call for the first iteration, where we already have the page. So far this was found by code inspection, but let's just CC stable as the fix is easy.
CVE-2024-57799 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: phy: rockchip: samsung-hdptx: Set drvdata before enabling runtime PM In some cases, rk_hdptx_phy_runtime_resume() may be invoked before platform_set_drvdata() is executed in ->probe(), leading to a NULL pointer dereference when using the return of dev_get_drvdata(). Ensure platform_set_drvdata() is called before devm_pm_runtime_enable().
CVE-2024-56782 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration() acpi_dev_hid_match() does not check for adev == NULL, dereferencing it unconditional. Add a check for adev being NULL before calling acpi_dev_hid_match(). At the moment acpi_quirk_skip_serdev_enumeration() is never called with a controller_parent without an ACPI companion, but better safe than sorry.
CVE-2024-56774 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: btrfs: add a sanity check for btrfs root in btrfs_search_slot() Syzbot reports a null-ptr-deref in btrfs_search_slot(). The reproducer is using rescue=ibadroots, and the extent tree root is corrupted thus the extent tree is NULL. When scrub tries to search the extent tree to gather the needed extent info, btrfs_search_slot() doesn't check if the target root is NULL or not, resulting the null-ptr-deref. Add sanity check for btrfs root before using it in btrfs_search_slot().
CVE-2024-56773 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: kunit: Fix potential null dereference in kunit_device_driver_test() kunit_kzalloc() may return a NULL pointer, dereferencing it without NULL check may lead to NULL dereference. Add a NULL check for test_state.
CVE-2024-56730 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: net/9p/usbg: fix handling of the failed kzalloc() memory allocation On the linux-next, next-20241108 vanilla kernel, the coccinelle tool gave the following error report: ./net/9p/trans_usbg.c:912:5-11: ERROR: allocation function on line 911 returns NULL not ERR_PTR on failure kzalloc() failure is fixed to handle the NULL return case on the memory exhaustion.
CVE-2024-56727 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: handle otx2_mbox_get_rsp errors in otx2_flows.c Adding error pointer check after calling otx2_mbox_get_rsp().
CVE-2024-56726 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: handle otx2_mbox_get_rsp errors in cn10k.c Add error pointer check after calling otx2_mbox_get_rsp().
CVE-2024-56711 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: drm/panel: himax-hx83102: Add a check to prevent NULL pointer dereference drm_mode_duplicate() could return NULL due to lack of memory, which will then call NULL pointer dereference. Add a check to prevent it.
CVE-2024-56702 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: bpf: Mark raw_tp arguments with PTR_MAYBE_NULL Arguments to a raw tracepoint are tagged as trusted, which carries the semantics that the pointer will be non-NULL. However, in certain cases, a raw tracepoint argument may end up being NULL. More context about this issue is available in [0]. Thus, there is a discrepancy between the reality, that raw_tp arguments can actually be NULL, and the verifier's knowledge, that they are never NULL, causing explicit NULL checks to be deleted, and accesses to such pointers potentially crashing the kernel. To fix this, mark raw_tp arguments as PTR_MAYBE_NULL, and then special case the dereference and pointer arithmetic to permit it, and allow passing them into helpers/kfuncs; these exceptions are made for raw_tp programs only. Ensure that we don't do this when ref_obj_id > 0, as in that case this is an acquired object and doesn't need such adjustment. The reason we do mask_raw_tp_trusted_reg logic is because other will recheck in places whether the register is a trusted_reg, and then consider our register as untrusted when detecting the presence of the PTR_MAYBE_NULL flag. To allow safe dereference, we enable PROBE_MEM marking when we see loads into trusted pointers with PTR_MAYBE_NULL. While trusted raw_tp arguments can also be passed into helpers or kfuncs where such broken assumption may cause issues, a future patch set will tackle their case separately, as PTR_TO_BTF_ID (without PTR_TRUSTED) can already be passed into helpers and causes similar problems. Thus, they are left alone for now. It is possible that these checks also permit passing non-raw_tp args that are trusted PTR_TO_BTF_ID with null marking. In such a case, allowing dereference when pointer is NULL expands allowed behavior, so won't regress existing programs, and the case of passing these into helpers is the same as above and will be dealt with later. Also update the failure case in tp_btf_nullable selftest to capture the new behavior, as the verifier will no longer cause an error when directly dereference a raw tracepoint argument marked as __nullable.
