CVE-2025-68292

The CVE-2025-68292 issue concerns the Linux kernel memfd hugetlb folio allocation. A path used by memfd bypassed the normal page fault handler (hugetlb_no_page), omitting three initialisation steps that could leak kernel memory or cause races: (1) folios not zeroed, risking information disclosure...

CVE-2025-68282

The CVE-2025-68282 issue is in the Linux kernel USB gadget UDC teardown: a race can cause a use-after-free in usb_gadget_state_work due to a concurrent event scheduling work during cleanup. The fix introduces a teardown flag and a state_lock spinlock in the usb_gadget struct; the flag is set duri...

CVE-2025-68264

In CVE-2025-68264, the Linux kernel ext4 inline data path is vulnerable to a race where i_inline_size can become stale between the initial size check and the actual write. Specifically, a concurrent xattr operation may change i_inline_size after ext4_get_max_inline_size() passes the check but bef...

CVE-2025-68264

In the Linux kernel, the following vulnerability has been resolved: ext4: refresh inline data size before write operations The cached ei-iinlinesize can become stale between the initial size check and when ext4updateinlinedata/ext4createinlinedata use it. Although ext4getmaxinlinesize reads the...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: ipc: fix use-after-free in ipcmsgsendrequest ipcmsgsendrequest waits for a generic netlink reply using an ipcmsgtableentry on the stack. The generic netlink handler handlegenericevent/handleresponse fills entry-response...

CVE-2025-68250 hung_task: fix warnings caused by unaligned lock pointers

In the Linux kernel, the following vulnerability has been resolved: hungtask: fix warnings caused by unaligned lock pointers The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned to use their lower bits for type encoding. However, as reported by Eero Tamminen, some...

CVE-2025-68250

CVE-2025-68250 affects the Linux kernel. The issue arises from an assumption that lock pointers are 4-byte aligned to use lower bits for type encoding, which fails on architectures with only 2-byte alignment (e.g., m68k). This causes two WARN_ON_ONCE checks to trigger in the hung_task blocker log...
