In the Linux kernel, the following vulnerability has been resolved: net: dpaa: Pad packets to ETH_ZLEN When sending packets under 60 bytes, up to three bytes of the buffer following the data may be leaked. Avoid this by extending all packets to ETH_ZLEN, ensuring nothing is leaked in the padding.

https://notcve.org/view.php?id=CVE-2024-46852
In the Linux kernel, the following vulnerability has been resolved: dma-buf: heaps: Fix off-by-one in CMA heap fault handler Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping. • https://git.kernel.org/stable/c/a5d2d29e24be8967ef78a1b1fb2292413e3b3df9 https://git.kernel.org/stable/c/007180fcb6cc4a93211d4cc45fef3f5ccccd56ae https://git.kernel.org/stable/c/79cce5e81d20fa9ad553be439d665ac3302d3c95 https://git.kernel.org/stable/c/84175dc5b2c932266a50c04e5ce342c30f817a2f https://git.kernel.org/stable/c/eb7fc8b65cea22f9038c52398c8b22849e9620ea https://git.kernel.org/stable/c/e79050882b857c37634baedbdcf7c2047c24cbff https://git.kernel.org/stable/c/ea5ff5d351b520524019f7ff7f9ce418de2dad87 •
