概要

AlmaLinux 主機缺少一或多個安全性更新。

說明

AlmaLinux 9.6 主機已安裝的套件會受到 TuxCare ALMALINUX9.6：CLSA-2026：1784278790 公告中所述弱點影響。

- 已解決 Linux 核心中的下列弱點：xfs: resample the data fork mapping after cycling ILOCK xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode, a data fork mapping, and a cow fork mapping. Unfortunately, these two helpers cycle the ILOCK to grab a transaction, which means that the mappings are stale as soon as we reacquire the ILOCK. Currently we refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but we don't refresh the data fork mapping beforehand, which means that the xfs_bmap_trim_cow in that function queries the refcount btree about the wrong physical blocks and returns an inaccurate value in *shared. If *shared is now false, the directio write proceeds with a stale data fork mapping. Fix this by querying the data fork mapping if the sequence counter changes across the ILOCK cycle. (CVE-2026-64600)
