| CVE-2025-40013 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: audioreach: fix potential null pointer dereference It is possible that the topology parsing function audioreach_widget_load_module_common() could return NULL or an error pointer. Add missing NULL check so that we do not dereference it. | ||||

| In the Linux kernel, the following vulnerability has been resolved: crypto: essiv - Check ssize for decryption and in-place encryption Move the ssize check to the start in essiv_aead_crypt so that it's also checked for decryption and in-place encryption. | ||||
| CVE-2025-40229 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme Currently, damon_destroy_scheme() only cleans up the filter list but leaves ops_filter untouched, which could lead to memory leaks when a scheme is destroyed. This patch ensures both filter and ops_filter are properly freed in damon_destroy_scheme(), preventing potential memory leaks. | ||||
| CVE-2025-40032 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: pci-epf-test: Add NULL check for DMA channels before release The fields dma_chan_tx and dma_chan_rx of the struct pci_epf_test can be NULL even after EPF initialization. Then it is prudent to check that they have non-NULL values before releasing the channels. Add the checks in pci_epf_test_clean_dma_chan(). Without the checks, NULL pointer dereferences happen and they can lead to a kernel panic in some cases: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000050 Call trace: dma_release_channel+0x2c/0x120 (P) pci_epf_test_epc_deinit+0x94/0xc0 [pci_epf_test] pci_epc_deinit_notify+0x74/0xc0 tegra_pcie_ep_pex_rst_irq+0x250/0x5d8 irq_thread_fn+0x34/0xb8 irq_thread+0x18c/0x2e8 kthread+0x14c/0x210 ret_from_fork+0x10/0x20 [mani: trimmed the stack trace] | ||||
| CVE-2025-40157 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: EDAC/i10nm: Skip DIMM enumeration on a disabled memory controller When loading the i10nm_edac driver on some Intel Granite Rapids servers, a call trace may appear as follows: UBSAN: shift-out-of-bounds in drivers/edac/skx_common.c:453:16 shift exponent -66 is negative ... __ubsan_handle_shift_out_of_bounds+0x1e3/0x390 skx_get_dimm_info.cold+0x47/0xd40 [skx_edac_common] i10nm_get_dimm_config+0x23e/0x390 [i10nm_edac] skx_register_mci+0x159/0x220 [skx_edac_common] i10nm_init+0xcb0/0x1ff0 [i10nm_edac] ... This occurs because some BIOS may disable a memory controller if there aren't any memory DIMMs populated on this memory controller. The DIMMMTR register of this disabled memory controller contains the invalid value ~0, resulting in the call trace above. Fix this call trace by skipping DIMM enumeration on a disabled memory controller. | ||||
| CVE-2025-40049 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Squashfs: fix uninit-value in squashfs_get_parent Syzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug. This is caused by open_by_handle_at() being called with a file handle containing an invalid parent inode number. In particular the inode number is that of a symbolic link, rather than a directory. Squashfs_get_parent() gets called with that symbolic link inode, and accesses the parent member field. unsigned int parent_ino = squashfs_i(inode)->parent; Because non-directory inodes in Squashfs do not have a parent value, this is uninitialised, and this causes an uninitialised value access. The fix is to initialise parent with the invalid inode 0, which will cause an EINVAL error to be returned. Regular inodes used to share the parent field with the block_list_start field. This is removed in this commit to enable the parent field to contain the invalid inode number 0. | ||||
| CVE-2025-40043 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: nfc: nci: Add parameter validation for packet data Syzbot reported an uninitialized value bug in nci_init_req, which was introduced by commit 5aca7966d2a7 ("Merge tag 'perf-tools-fixes-for-v6.17-2025-09-16' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools"). This bug arises due to very limited and poor input validation that was done at nic_valid_size(). This validation only validates the skb->len (directly reflects size provided at the userspace interface) with the length provided in the buffer itself (interpreted as NCI_HEADER). This leads to the processing of memory content at the address assuming the correct layout per what opcode requires there. This leads to the accesses to buffer of `skb_buff->data` which is not assigned anything yet. Following the same silent drop of packets of invalid sizes at `nic_valid_size()`, add validation of the data in the respective handlers and return error values in case of failure. Release the skb if error values are returned from handlers in `nci_nft_packet` and effectively do a silent drop Possible TODO: because we silently drop the packets, the call to `nci_request` will be waiting for completion of request and will face timeouts. These timeouts can get excessively logged in the dmesg. A proper handling of them may require to export `nci_request_cancel` (or propagate error handling from the nft packets handlers). | ||||
| CVE-2025-40231 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: vsock: fix lock inversion in vsock_assign_transport() Syzbot reported a potential lock inversion deadlock between vsock_register_mutex and sk_lock-AF_VSOCK when vsock_linger() is called. The issue was introduced by commit 687aa0c5581b ("vsock: Fix transport_* TOCTOU") which added vsock_register_mutex locking in vsock_assign_transport() around the transport->release() call, that can call vsock_linger(). vsock_assign_transport() can be called with sk_lock held. vsock_linger() calls sk_wait_event() that temporarily releases and re-acquires sk_lock. During this window, if another thread hold vsock_register_mutex while trying to acquire sk_lock, a circular dependency is created. Fix this by releasing vsock_register_mutex before calling transport->release() and vsock_deassign_transport(). This is safe because we don't need to hold vsock_register_mutex while releasing the old transport, and we ensure the new transport won't disappear by obtaining a module reference first via try_module_get(). | ||||
| CVE-2025-68179 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390: Disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP As reported by Luiz Capitulino enabling HVO on s390 leads to reproducible crashes. The problem is that kernel page tables are modified without flushing corresponding TLB entries. Even if it looks like the empty flush_tlb_all() implementation on s390 is the problem, it is actually a different problem: on s390 it is not allowed to replace an active/valid page table entry with another valid page table entry without the detour over an invalid entry. A direct replacement may lead to random crashes and/or data corruption. In order to invalidate an entry special instructions have to be used (e.g. ipte or idte). Alternatively there are also special instructions available which allow to replace a valid entry with a different valid entry (e.g. crdte or cspg). Given that the HVO code currently does not provide the hooks to allow for an implementation which is compliant with the s390 architecture requirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which is basically a revert of the original patch which enabled it. | ||||
| CVE-2022-50888 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom: q6v5: Fix potential null-ptr-deref in q6v5_wcss_init_mmio() q6v5_wcss_init_mmio() will call platform_get_resource_byname() that may fail and return NULL. devm_ioremap() will use res->start as input, which may causes null-ptr-deref. Check the ret value of platform_get_resource_byname() to avoid the null-ptr-deref. | ||||
| CVE-2022-50859 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: cifs: Fix the error length of VALIDATE_NEGOTIATE_INFO message Commit d5c7076b772a ("smb3: add smb3.1.1 to default dialect list") extend the dialects from 3 to 4, but forget to decrease the extended length when specific the dialect, then the message length is larger than expected. This maybe leak some info through network because not initialize the message body. After apply this patch, the VALIDATE_NEGOTIATE_INFO message length is reduced from 28 bytes to 26 bytes. | ||||

| In the Linux kernel, the following vulnerability has been resolved: PCI: rcar-host: Pass proper IRQ domain to generic_handle_domain_irq() Starting with commit dd26c1a23fd5 ("PCI: rcar-host: Switch to msi_create_parent_irq_domain()"), the MSI parent IRQ domain is NULL because the object of type struct irq_domain_info passed to: msi_create_parent_irq_domain() -> irq_domain_instantiate()() -> __irq_domain_instantiate() has no reference to the parent IRQ domain. Using msi->domain->parent as an argument for generic_handle_domain_irq() leads to below error: "Unable to handle kernel NULL pointer dereference at virtual address" This error was identified while switching the upcoming RZ/G3S PCIe host controller driver to msi_create_parent_irq_domain() (which was using a similar pattern to handle MSIs (see link section)), but it was not tested on hardware using the pcie-rcar-host controller driver due to lack of hardware.

| In the Linux kernel, the following vulnerability has been resolved: comedi: fix divide-by-zero in comedi_buf_munge() The comedi_buf_munge() function performs a modulo operation `async->munge_chan %= async->cmd.chanlist_len` without first checking if chanlist_len is zero. If a user program submits a command with chanlist_len set to zero, this causes a divide-by-zero error when the device processes data in the interrupt handler path. Add a check for zero chanlist_len at the beginning of the function, similar to the existing checks for !map and CMDF_RAWDATA flag. When chanlist_len is zero, update munge_count and return early, indicating the data was handled without munging. This prevents potential kernel panics from malformed user commands. | ||||
