CVE-2026-64152

CVE-2026-64152 affects the Linux kernel iommu path. The issue arises when an unmap error in the iommu_debug flow occurs in an error path that did not establish the original iommu_debug_map, causing mis-tracing and unbalanced tracking. Fix: move the unmap error handling into iommu_map_nosync() and...

CVE-2024-50067 uprobe: avoid out-of-bounds memory access of fetching args

In the Linux kernel, the following vulnerability has been resolved: uprobe: avoid out-of-bounds memory access of fetching args Uprobe needs to fetch args into a percpu buffer, and then copy to ring buffer to avoid non-atomic context problem. Sometimes user-space strings, arrays can be very large,...

CVE-2024-46785 eventfs: Use list_del_rcu() for SRCU protected list variable

In the Linux kernel, the following vulnerability has been resolved: eventfs: Use listdelrcu for SRCU protected list variable Chi Zhiling reported: We found a null pointer accessing in tracefs1, the reason is that the variable 'eichild' is set to LISTPOISON1, that means the list was removed in...

CVE-2021-46933 usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear.

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Clear ffseventfd in ffsdataclear. ffsdataclear is indirectly called from both ffsfskillsb and ffsep0release, so it ends up being called twice when userland closes ep0 and then unmounts ffs. If userland provided ...
