CVE-2026-23194

In the Linux kernel, the following vulnerability has been resolved: rustbinder: correctly handle FDA objects of length zero Fix a bug where an empty FDA fd array object with 0 fds would cause an out-of-bounds error. The previous implementation used skip == 0 to mean "this is a pointer fixup", but...

CVE-2026-23194

CVE-2026-23194 relates to the Linux kernel rust_binder handling of FDA objects of length zero. The issue was a out-of-bounds write when an empty fd-array (FDA) with 0 fds was processed, caused by treating skip == 0 as a special “pointer fixup.” The fix replaces this zero-special-case pattern (ori...

CVE-2025-71221 dmaengine: mmp_pdma: Fix race condition in mmp_pdma_residue()

In the Linux kernel, the following vulnerability has been resolved: dmaengine: mmppdma: Fix race condition in mmppdmaresidue Add proper locking in mmppdmaresidue to prevent use-after-free when accessing descriptor list and descriptor contents. The race occurs when multiple threads call txstatus...

CVE-2025-71221

CVE-2025-71221: The Linux kernel mmp_pdma driver contained a race in mmp_pdma_residue() that could cause use-after-free when descriptors are freed while tx_status() iterates the descriptor list. The race occurs as CPU0 unwinds the descriptor list without proper locking while CPU1's tasklet can fr...
