The Linux kernel's bpf redirect helpers previously crashed when no bpf_net_context existed. The fix involves making these helpers reject redirects in such cases, preventing the crash. This change ensures system stability and security by preventing NULL dereferences. Linux kernel developers and maintainers should assess exposure and verify the patched version is deployed. The fix prevents potential denial- [truncated]
A null dereference vulnerability was found in the Linux kernel's drm/vc4 component. The hvs and v3d drivers use dev_get_drvdata(master) in their unbind functions, which can lead to a null pointer dereference error when the vc4-drm is removed before its dependent drivers. This issue affects Linux kernel maintainers and users, system administrators, and security teams responsible for patching and vulnerabil [truncated]
A Linux kernel vulnerability was resolved, addressing an integer overflow issue in the tipc_recvmsg() and tipc_recvstream() functions. The vulnerability could lead to a kernel panic. The issue arises when the buflen exceeds INT_MAX, causing a wrap to a negative value, which then propagates to simple_copy_to_iter(), triggering a WARN_ON. This issue requires verification of exposure and application of patch [truncated]
A vulnerability in the Linux kernel's netlink drop monitor subsystem can lead to an information leak. The `net_dm_packet_report_fill` and `net_dm_hw_packet_report_fill` functions do not properly initialize padding bytes when constructing the `NET_DM_ATTR_PAYLOAD` attribute, potentially leaking 1-3 uninitialized bytes to user space. This issue was reported by an unnamed source and confirmed by the Linux ke [truncated]
A vulnerability in the Linux kernel's drop_monitor component can lead to an skb_over_panic() when __nla_reserve() or skb_put() is called, due to under-estimation of SKB size. This issue arises from the use of nla_put_u64_64bit() to append 64-bit attributes without proper size calculations. The vulnerability affects Linux kernel versions and configurations, potentially allowing for denial-of-service (DoS) [truncated]
A vulnerability in the Linux kernel's drop_monitor component has been addressed. The issue involves improper synchronization of u64_stats updates, which could lead to seqcount state corruption or inaccurate stats values on 32-bit architectures when interrupts are nested. This problem arises because u64_stats_update_begin() disables preemption but not interrupts, relying on seqcount writes to ensure atomic [truncated]
The Linux kernel's DRM bridge driver was found to be using the deprecated UNIVERSAL_DEV_PM_OPS() macro, leading to incorrect power management operations. This could result in warnings during suspend operations due to attempts to disable already-disabled clocks. The issue was addressed by replacing UNIVERSAL_DEV_PM_OPS() with RUNTIME_PM_OPS(). Affected product deployments should be reviewed for exposure, a [truncated]
The Linux kernel's drm/dp/mst component has a vulnerability (CVE-2026-68279) that allows for out-of-bounds reads in remote DPCD/I2C sideband reply parsers. This could potentially allow a malicious MST hub to cause the kernel to read past the received data, accessing adjacent memory. The issue has been resolved with additional checks to prevent such out-of-bounds reads. Linux kernel users and administrator [truncated]
The Linux kernel has a vulnerability in drm/dp/mst that could lead to buffer overflows due to improper handling of sideband chunk accumulation. This issue arises from drm_dp_sideband_append_payload() processing device-provided sideband reply data. There are three primary bugs: a zero-length curchunk_len underflow, a chunk[48] overflow, and a msg[256] overflow. These bugs can be exploited by any DP MST dev [truncated]
The Linux kernel has a vulnerability in drm/dp/mst sideband reply parsers, allowing for OOB reads on 2-byte fields. This affects Linux kernel users and administrators, cybersecurity teams, and developers working with drm/dp/mst functionality. The fix involves using a combined check to prevent such reads. The CVE record was published on 2026-08-10T13:20:16.803Z and has not been modified since then. To veri [truncated]
A Linux kernel vulnerability was resolved, addressing a drm/amdgpu/gfx cleaner shader IB buffer overflow. The cleaner shader sysfs path allocates a 16-dword (64 byte) IB but incorrectly fills (align_mask + 1) dwords, causing a kernel page fault. The IB only needs to be a minimal NOP shell to schedule the job. This issue affects Linux kernel users and administrators, who should review system configurations [truncated]
The Linux kernel has a vulnerability in the drm/amdgpu component. The AMDGPU_GEM_OP_GET_MAPPING_INFO path of amdgpu_gem_op_ioctl() does not check the result of amdgpu_vm_bo_find(), leading to a potential NULL pointer dereference. This issue can be triggered by any process able to issue the ioctl, simply by requesting mapping info for an unmapped BO.
A buffer overflow vulnerability was found in the Linux kernel's drm/xe/guc component. The vulnerability occurs when calculating the size of the steered register extarray, which uses only the geometry DSS mask (g_dss_mask) to determine the number of entries to allocate. However, the filling loop uses for_each_dss_steering(), which iterates over for_each_dss(), defined as the union of g_dss_mask and c_dss_m [truncated]
The Linux kernel vulnerability, CVE-2026-68273, is a HIGH severity issue affecting the drm/amdgpu context pstate override handling. This vulnerability could lead to use-after-free and NULL pointer dereferences at context initialization time, potentially impacting the security of Linux-based systems. The issue arises from several problems in the context pstate handling code, including the lack of proper lo [truncated]
The Linux kernel has a vulnerability in the drm/amdgpu driver that has been resolved. The vulnerability is related to the validation of the CP_GFX_SHADOW chunk size in the CS pass1. A minimum-length check has been added for the AMDGPU_CHUNK_ID_CP_GFX_SHADOW chunk in amdgpu_cs_pass1(). This check matches the gate already present for the IB, FENCE, and BO_HANDLES chunk types. The vulnerability could be expl [truncated]
The Linux kernel vulnerability CVE-2026-68270 is related to drm/sysfb, specifically with calculating the visible size of the system framebuffer. The calculation uses 32-bit arithmetics, which can overflow if the values for height and stride are large. The issue is resolved by using mul_u32_u32(). Affected Linux kernel users and administrators should be aware of this vulnerability and take necessary action [truncated]
The Linux kernel's drm/i915/gem component had a missing Spectre mitigation for userspace-controlled parallel submission slots. This issue has been resolved by adding the necessary nospec protection. The vulnerability was discovered using AI-assisted static analysis and confirmed by Intel Product Security. Linux kernel users should review and apply available updates to mitigate potential Spectre-related ri [truncated]
A security vulnerability has been identified and resolved in the Linux kernel, specifically in the drm/xe/rtp component. The issue involved unconditional whitelisting of OA registers, which is a security violation. The fix sets the RING_FORCE_TO_NONPRIV_DENY bit in OA nonpriv slots to prevent OA registers from being whitelisted by default after certain system events.
The Linux kernel's drm/xe component has a use-after-free vulnerability. An imported dma-buf BO is created with a reservation object that is the exporter's dma_buf->resv. However, the importer only takes a dma-buf reference after a successful dma_buf_dynamic_attach(). Until then, nothing keeps the exporter alive, allowing for a use-after-free if the exporter is freed while the BO still references its resv. [truncated]
