18 Jun 2025 — In the Linux kernel, the following vulnerability has been resolved: mm/gup: fix FOLL_FORCE COW security issue and remove FOLL_COW Ever since the Dirty COW (CVE-2016-5195) security issue happened, we know that FOLL_FORCE can be possibly dangerous, especially if there are races that can be exploited by user space. Right now, it would be sufficient to have some code that sets a PTE of a R/O-mapped shared page dirty, in order for it to erroneously become writable by FOLL_FORCE. The implications of setting a wri... • https://git.kernel.org/stable/c/9ae0f87d009ca6c4aab2882641ddfc319727e3db •

18 Jun 2025 — In the Linux kernel, the following vulnerability has been resolved: net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READY Only set MLX5_LAG_FLAG_NDEVS_READY if both netdevices are registered. Doing so guarantees that both ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev have valid pointers when MLX5_LAG_FLAG_NDEVS_READY is set. The core issue is asymmetry in setting MLX5_LAG_FLAG_NDEVS_READY and clearing it. Setting it is done wrongly when both ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].de... • https://git.kernel.org/stable/c/8a66e45859797e5dd77ff17dd37781f99d5f5b9b •

18 Jun 2025 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix possible memory leak in btrfs_get_dev_args_from_path() In btrfs_get_dev_args_from_path(), btrfs_get_bdev_and_sb() can fail if the path is invalid. In this case, btrfs_get_dev_args_from_path() returns directly without freeing args->uuid and args->fsid allocated before, which causes memory leak. To fix these possible leaks, when btrfs_get_bdev_and_sb() fails, btrfs_put_dev_args_from_path() is called to clean up the memory.

18 Jun 2025 — In the Linux kernel, the following vulnerability has been resolved: writeback: avoid use-after-free after removing device When a disk is removed, bdi_unregister gets called to stop further writeback and wait for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation dwork after this has completed, which can result in the timer attempting to access the just freed bdi_writeback.
