jira LE-3428 cve CVE-2025-21919 Rebuild_History Non-Buildable kernel-5.14.0-570.23.1.el9_6 commit-author Zecheng Li <[email protected]> commit 3b4035d child_cfs_rq_on_list attempts to convert a 'prev' pointer to a cfs_rq. This 'prev' pointer can originate from struct rq's leaf_cfs_rq_list, making the conversion invalid and potentially leading to memory corruption. Depending on the relative positions of leaf_cfs_rq_list and the task group (tg) pointer within the struct, this can cause a memory fault or access garbage data. The issue arises in list_add_leaf_cfs_rq, where both cfs_rq->leaf_cfs_rq_list and rq->leaf_cfs_rq_list are added to the same leaf list. Also, rq->tmp_alone_branch can be set to rq->leaf_cfs_rq_list. This adds a check `if (prev == &rq->leaf_cfs_rq_list)` after the main conditional in child_cfs_rq_on_list. This ensures that the container_of operation will convert a correct cfs_rq struct. This check is sufficient because only cfs_rqs on the same CPU are added to the list, so verifying the 'prev' pointer against the current rq's list head is enough. Fixes a potential memory corruption issue that due to current struct layout might not be manifesting as a crash but could lead to unpredictable behavior when the layout changes.

jira LE-3428 cve CVE-2025-21883 Rebuild_History Non-Buildable kernel-5.14.0-570.23.1.el9_6 commit-author Paul Greenwalt <[email protected]> commit 59f4d59 E830 adds hardware support to prevent the VF from overflowing the PF mailbox with VIRTCHNL messages. E830 will use the hardware feature (ICE_F_MBX_LIMIT) instead of the software solution ice_is_malicious_vf(). To prevent a VF from overflowing the PF, the PF sets the number of messages per VF that can be in the PF's mailbox queue (ICE_MBX_OVERFLOW_WATERMARK). When the PF processes a message from a VF, the PF decrements the per VF message count using the E830_MBX_VF_DEC_TRIG register.

Default Rx VSI is also used by promiscuous mode.
