| CVE-2024-50091 | 1 Linux | 1 Linux Kernel | 2025-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm vdo: don't refer to dedupe_context after releasing it Clear the dedupe_context pointer in a data_vio whenever ownership of the context is lost, so that vdo can't examine it accidentally. | ||||
| CVE-2024-50088 | 1 Linux | 1 Linux Kernel | 2025-10-01 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free in add_inode_ref() The add_inode_ref() function does not initialize the "name" struct when it is declared. If any of the following calls to "read_one_inode() returns NULL, dir = read_one_inode(root, parent_objectid); if (!dir) { ret = -ENOENT; goto out; } inode = read_one_inode(root, inode_objectid); if (!inode) { ret = -EIO; goto out; } then "name.name" would be freed on "out" before being initialized. out: ... kfree(name.name); This issue was reported by Coverity with CID 1526744. | ||||
| CVE-2024-50087 | 1 Linux | 1 Linux Kernel | 2025-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free on read_alloc_one_name() error The function read_alloc_one_name() does not initialize the name field of the passed fscrypt_str struct if kmalloc fails to allocate the corresponding buffer. Thus, it is not guaranteed that fscrypt_str.name is initialized when freeing it. This is a follow-up to the linked patch that fixes the remaining instances of the bug introduced by commit e43eec81c516 ("btrfs: use struct qstr instead of name and namelen pairs"). | ||||
| CVE-2024-57943 | 1 Linux | 1 Linux Kernel | 2025-10-01 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: exfat: fix the new buffer was not zeroed before writing Before writing, if a buffer_head marked as new, its data must be zeroed, otherwise uninitialized data in the page cache will be written. So this commit uses folio_zero_new_buffers() to zero the new buffers before ->write_end(). | ||||

| CVE-2021-47531 | 1 Linux | 1 Linux Kernel | 2025-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix mmap to include VM_IO and VM_DONTDUMP In commit 510410bfc034 ("drm/msm: Implement mmap as GEM object function") we switched to a new/cleaner method of doing things. That's good, but we missed a little bit. Before that commit, we used to _first_ run through the drm_gem_mmap_obj() case where `obj->funcs->mmap()` was NULL. That meant that we ran: vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP; vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags)); vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot); ...and _then_ we modified those mappings with our own. Now that `obj->funcs->mmap()` is no longer NULL we don't run the default code. It looks like the fact that the vm_flags got VM_IO / VM_DONTDUMP was important because we're now getting crashes on Chromebooks that use ARC++ while logging out. Specifically a crash that looks like this (this is on a 5.10 kernel w/ relevant backports but also seen on a 5.15 kernel): Unable to handle kernel paging request at virtual address ffffffc008000000 Mem abort info: ESR = 0x96000006 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000006 CM = 0, WnR = 0 swapper pgtable: 4k pages, 39-bit VAs, pgdp=000000008293d000 [ffffffc008000000] pgd=00000001002b3003, p4d=00000001002b3003, pud=00000001002b3003, pmd=0000000000000000 Internal error: Oops: 96000006 [#1] PREEMPT SMP [...] CPU: 7 PID: 15734 Comm: crash_dump64 Tainted: G W 5.10.67 #1 [...] Hardware name: Qualcomm Technologies, Inc. sc7280 IDP SKU2 platform (DT) pstate: 80400009 (Nzcv daif +PAN -UAO -TCO BTYPE=--) pc : __arch_copy_to_user+0xc0/0x30c lr : copyout+0xac/0x14c [...] Call trace: __arch_copy_to_user+0xc0/0x30c copy_page_to_iter+0x1a0/0x294 process_vm_rw_core+0x240/0x408 process_vm_rw+0x110/0x16c __arm64_sys_process_vm_readv+0x30/0x3c el0_svc_common+0xf8/0x250 do_el0_svc+0x30/0x80 el0_svc+0x10/0x1c el0_sync_handler+0x78/0x108 el0_sync+0x184/0x1c0 Code: f8408423 f80008c3 910020c6 36100082 (b8404423) Let's add the two flags back in. While we're at it, the fact that we aren't running the default means that we _don't_ need to clear out VM_PFNMAP, so remove that and save an instruction. NOTE: it was confirmed that VM_IO was the important flag to fix the problem I was seeing, but adding back VM_DONTDUMP seems like a sane thing to do so I'm doing that too. | ||||
| CVE-2024-42275 | 1 Linux | 1 Linux Kernel | 2025-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/client: Fix error code in drm_client_buffer_vmap_local() This function accidentally returns zero/success on the failure path. It leads to locking issues and an uninitialized *map_copy in the caller. | ||||
| CVE-2025-59535 | 1 Dnnsoftware | 2 Dnn Platform, Dotnetnuke | 2025-09-29 | 6.5 Medium |
| DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.1.0, arbitrary themes can be loaded through query parameters. If an installed theme had a vulnerability, even if it was not used on any page, this could be loaded on unsuspecting clients without knowledge of the site owner. This issue has been patched in version 10.1.0. | ||||
| CVE-2025-38631 | 1 Linux | 1 Linux Kernel | 2025-09-29 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: clk: imx95-blk-ctl: Fix synchronous abort When enabling runtime PM for clock suppliers that also belong to a power domain, the following crash is thrown: error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP Workqueue: events_unbound deferred_probe_work_func pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : clk_mux_get_parent+0x60/0x90 lr : clk_core_reparent_orphans_nolock+0x58/0xd8 Call trace: clk_mux_get_parent+0x60/0x90 clk_core_reparent_orphans_nolock+0x58/0xd8 of_clk_add_hw_provider.part.0+0x90/0x100 of_clk_add_hw_provider+0x1c/0x38 imx95_bc_probe+0x2e0/0x3f0 platform_probe+0x70/0xd8 Enabling runtime PM without explicitly resuming the device caused the power domain cut off after clk_register() is called. As a result, a crash happens when the clock hardware provider is added and attempts to access the BLK_CTL register. Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable() and getting rid of the pm_runtime_disable() in the cleanup path. | ||||
| CVE-2024-27411 | 1 Linux | 1 Linux Kernel | 2025-09-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: keep DMA buffers required for suspend/resume Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly. This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze. This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init. | ||||
| CVE-2024-42113 | 1 Linux | 1 Linux Kernel | 2025-09-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: txgbe: initialize num_q_vectors for MSI/INTx interrupts When using MSI/INTx interrupts, wx->num_q_vectors is uninitialized. Thus there will be kernel panic in wx_alloc_q_vectors() to allocate queue vectors. | ||||

| A flaw was found in Yelp. The Gnome user help application allows the help document to execute arbitrary scripts. This vulnerability allows malicious users to input help documents, which may exfiltrate user files to an external environment. | ||||
| CVE-2025-26599 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-09-25 | 7.8 High |
| An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later. | ||||
| CVE-2021-47434 | 1 Linux | 1 Linux Kernel | 2025-09-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xhci: Fix command ring pointer corruption while aborting a command The command ring pointer is located at [6:63] bits of the command ring control register (CRCR). All the control bits like command stop, abort are located at [0:3] bits. While aborting a command, we read the CRCR and set the abort bit and write to the CRCR. The read will always give command ring pointer as all zeros. So we essentially write only the control bits. Since we split the 64 bit write into two 32 bit writes, there is a possibility of xHC command ring stopped before the upper dword (all zeros) is written. If that happens, xHC updates the upper dword of its internal command ring pointer with all zeros. Next time, when the command ring is restarted, we see xHC memory access failures. Fix this issue by only writing to the lower dword of CRCR where all control bits are located. | ||||
| CVE-2025-58749 | 1 Bytecodealliance | 1 Webassembly Micro Runtime | 2025-09-20 | 5.3 Medium |
| WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. In WAMR versions prior to 2.4.2, when running in LLVM-JIT mode, the runtime cannot exit normally when executing WebAssembly programs containing a memory.fill instruction where the first operand (memory address pointer) is greater than or equal to 2147483648 bytes (2GiB). This causes the runtime to hang in release builds or crash in debug builds due to accessing an invalid pointer. The issue does not occur in FAST-JIT mode or other runtime tools. This has been fixed in version 2.4.2. | ||||
| CVE-2022-48644 | 1 Linux | 1 Linux Kernel | 2025-09-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: avoid disabling offload when it was never enabled In an incredibly strange API design decision, qdisc->destroy() gets called even if qdisc->init() never succeeded, not exclusively since commit 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation"), but apparently also earlier (in the case of qdisc_create_dflt()). The taprio qdisc does not fully acknowledge this when it attempts full offload, because it starts off with q->flags = TAPRIO_FLAGS_INVALID in taprio_init(), then it replaces q->flags with TCA_TAPRIO_ATTR_FLAGS parsed from netlink (in taprio_change(), tail called from taprio_init()). But in taprio_destroy(), we call taprio_disable_offload(), and this determines what to do based on FULL_OFFLOAD_IS_ENABLED(q->flags). But looking at the implementation of FULL_OFFLOAD_IS_ENABLED() (a bitwise check of bit 1 in q->flags), it is invalid to call this macro on q->flags when it contains TAPRIO_FLAGS_INVALID, because that is set to U32_MAX, and therefore FULL_OFFLOAD_IS_ENABLED() will return true on an invalid set of flags. As a result, it is possible to crash the kernel if user space forces an error between setting q->flags = TAPRIO_FLAGS_INVALID, and the calling of taprio_enable_offload(). This is because drivers do not expect the offload to be disabled when it was never enabled. The error that we force here is to attach taprio as a non-root qdisc, but instead as child of an mqprio root qdisc: $ tc qdisc add dev swp0 root handle 1: \ mqprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0 $ tc qdisc replace dev swp0 parent 1:1 \ taprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 base-time 0 \ sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \ flags 0x0 clockid CLOCK_TAI Unable to handle kernel paging request at virtual address fffffffffffffff8 [fffffffffffffff8] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 96000004 [#1] PREEMPT SMP Call trace: taprio_dump+0x27c/0x310 vsc9959_port_setup_tc+0x1f4/0x460 felix_port_setup_tc+0x24/0x3c dsa_slave_setup_tc+0x54/0x27c taprio_disable_offload.isra.0+0x58/0xe0 taprio_destroy+0x80/0x104 qdisc_create+0x240/0x470 tc_modify_qdisc+0x1fc/0x6b0 rtnetlink_rcv_msg+0x12c/0x390 netlink_rcv_skb+0x5c/0x130 rtnetlink_rcv+0x1c/0x2c Fix this by keeping track of the operations we made, and undo the offload only if we actually did it.
