16 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: usbnet:fix NPE during rx_complete Missing usbnet_going_away Check in Critical Path. The usb_submit_urb function lacks a usbnet_going_away validation, whereas __usbnet_queue_skb includes this check. This inconsistency creates a race condition where: A URB request may succeed, but the corresponding SKB data fails to be queued. Subsequent processes: (e.g., rx_complete → defer_bh → __skb_unlink(skb, list)) attempt to access skb->next, triggerin... • https://git.kernel.org/stable/c/b80aacfea6e8d6ed6e430aa13922d6ccf044415a •

16 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: LoongArch: Increase ARCH_DMA_MINALIGN up to 16 ARCH_DMA_MINALIGN is 1 by default, but some LoongArch-specific devices (such as APBDMA) require 16 bytes alignment. When the data buffer length is too small, the hardware may make an error writing cacheline. Thus, it is dangerous to allocate a small memory buffer for DMA. It's always safe to define ARCH_DMA_MINALIGN as L1_CACHE_BYTES but unnecessary (kmalloc() need small memory objects). Theref... • https://git.kernel.org/stable/c/f39af67f03b564b763b06e44cb960c10a382d54a •

16 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Don't override subprog's return value The verifier test `calls: div by 0 in subprog` triggers a panic at the ld.bu instruction. The ld.bu insn is trying to load byte from memory address returned by the subprog. The subprog actually set the correct address at the a5 register (dedicated register for BPF return values). But at commit 73c359d1d356 ("LoongArch: BPF: Sign-extend return values") we also sign extended a5 to the a0 r... • https://git.kernel.org/stable/c/0c8d50501bc13cacecc19caaddc10db372592a39 •
