CVE-2026-63884 is a potential Use-After-Free (UAF) vulnerability in the Linux kernel's drm/i915 component. The vulnerability arises from a race condition in the TTM object purge process. Specifically, the bo->ttm object might be changed by calling ttm_bo_validate(), which could lead to a UAF when casting it to an i915_tt object later. This issue was reported by a user under heavy use on DG2 and has been r [truncated]
A vulnerability in the Linux kernel's serial: qcom_geni component can cause a kfifo underflow when uart_flush_buffer() runs before the DMA completion IRQ is delivered. This can lead to the submission of a DMA transfer of stale buffer data. Linux kernel users and maintainers should review and apply patches for CVE-2026-63883. The vulnerability has a medium defensive priority.
The Linux kernel has a vulnerability in the drm/amdkfd component, specifically in the kfd debugger. An integer overflow occurs in the get_queue_ids() function when calculating array_size, which could lead to a potential vulnerability on 32-bit size_t builds. The issue has been resolved by using the array_size() function, which saturates to SIZE_MAX on overflow. This vulnerability can affect Linux kernel u [truncated]
The Linux kernel was vulnerable to a lock leak in the AMDGPU_GEM_OP_GET_MAPPING_INFO branch of amdgpu_gem_op_ioctl(). This could lead to an unprivileged-local denial of service against the caller's GPU context. The vulnerability exists due to a failure to properly release resources in the event of a kvcalloc() failure, resulting in a lock leak. This issue affects Linux kernel versions and could be mitigat [truncated]
A vulnerability was resolved in the Linux kernel related to the drm/amdgpu component. The issue involves the amdgpu_hmm_range_get_pages function. According to the provided information, the notifier sequence must only be read once to avoid working with invalid pages. The fix also addresses coding style improvements. This vulnerability affects Linux kernel users and administrators, particularly those utiliz [truncated]
The Linux kernel was vulnerable to an allocation issue in the drm/amdgpu component. The function kvcalloc at amdgpu_gem.c:1050 used the user-supplied num_entries directly without an upper bounds check, potentially leading to a kernel WARNING, TAINT_WARN, and panic on systems with CONFIG_PANIC_ON_WARN=y. This issue has been resolved by adding a size bounds check before invoking kvzalloc to reject oversized [truncated]
A Linux kernel vulnerability, CVE-2026-63877, was resolved by converting the serial: dz driver to use a platform device, preventing a crash during the initialization of the first serial port.

The fix was applied through the Li [truncated]
A Linux kernel vulnerability, CVE-2026-63875, was resolved by flushing the walk cache when unsharing PMD tables on arm64. The issue arose because the aarch64 tlb_flush() only checked tlb->freed_tables, not tlb->unshared_tables, leading to stale PMD page table entries in the walk cache after unshare. This could cause incorrect page table walks. The fix includes unshared_tables in the check, ensuring TLBF_N [truncated]
A vulnerability was found in the Linux kernel's net: mctp: usb module. The issue involves a race condition between urb completion and rx_retry cancellation. When the ndo_stop function is called, it sets the ->stopped flag and cancels the rx_retry work. However, there's a possibility that an urb could be queued after setting ->stopped and before cancelling the rx_retry work. This could lead to the urb comp [truncated]
A vulnerability was found in the Linux kernel. The issue is a reference leak in the aie2_populate_range() function, which can cause a mm_struct reference to be leaked. The issue was resolved by adding a missing mmput() call before jumping to the again label. This vulnerability affects Linux kernel users and administrators, who should ensure their systems are up-to-date with the latest kernel patches to pr [truncated]
A Linux kernel vulnerability, CVE-2026-63872, was resolved in esp_output_tail(). The issue involved a page frag reference leak on skb_to_sgvec failure. When esp->inplace is false, old skb page frags are replaced with a new page from the xfrm page_frag cache. However, if the second skb_to_sgvec() call fails, the old page frag references are not released. The fix adds a bool parameter to esp_ssg_unref() to [truncated]

A vulnerability in the Linux kernel's ieee802154: 6lowpan implementation could allow an attacker to transmit non-IPv6 packets, potentially leading to uninitialized data usage. The issue has been resolved by only accepting IPv6 packets in lowpan_xmit(). This vulnerability affects Linux kernel maintainers, network administrators, and users of 6LoWPAN interfaces. The vulnerability has a medium defensive priority.
The Linux kernel has a vulnerability in the ieee80211_parse_tx_radiotap function, which is used to parse the radiotap header of an injected frame. When the IEEE80211_RADIOTAP_ANTENNA value is used directly as a shift count, it can lead to undefined behavior when the value is greater than 64. This vulnerability affects users of the Linux kernel, particularly those using wireless networking. The issue is ca [truncated]
The Linux kernel has a vulnerability in the GARP attribute parser, which incorrectly calculates the data length. This leads to ignored Join/Leave events, affecting common attributes like GVRP VLAN registration. The vulnerability has been resolved in newer kernel versions.
