21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential oob read in nilfs_btree_check_delete() The function nilfs_btree_check_delete(), which checks whether degeneration to direct mapping occurs before deleting a b-tree entry, causes memory access outside the block buffer when retrieving the maximum key if the root node has no entries. This does not usually happen because b-tree mappings with 0 child nodes are never created by mkfs.nilfs2 or nilfs2 itself. However, it can h... • https://git.kernel.org/stable/c/17c76b0104e4a6513983777e1a17e0297a12b0c4 •

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Added NULL check for lookup_atid The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the `act_establish()` and `act_open_rpl()` functions. Add a NULL check to prevent null pointer dereferencing. Found by Linux Verification Center (linuxtesting.org) with SVACE.

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: vhost_vdpa: assign irq bypass producer token correctly We used to call irq_bypass_unregister_producer() in vhost_vdpa_setup_vq_irq() which is problematic as we don't know if the token pointer is still valid or not. Actually, we use the eventfd_ctx as the token so the life cycle of the token should be bound to the VHOST_SET_VRING_CALL instead of vhost_vdpa_setup_vq_irq() which could be called by set_status(). Fixing this by setting up irq by... • https://git.kernel.org/stable/c/2cf1ba9a4d15cb78b96ea97f727b93382c3f9a60 •

And if the process has called personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for RW pages, this will actually result in remapping the pages to RWX, bypassing a W^X policy enforced by SELinux.
