CVE-2024-35957

CVE-2024-35957 is a vulnerability in the Linux kernel's Intel Virtualization Technology for Directed I/O VT-d subsystem. The issue stems from an incorrect assumption that each device has a unique source ID, leading to potential conflicts and system warnings during the IOMMU probe process. This fl...

CVE-2024-35941

REJECTED CVE A use-after-free vulnerability was identified in the Linux kernel's net subsystem, specifically in skbuff handling. The issue arises from an overflow of the skb-networkheader a u16 value, causing skbnetworkoffsetskb to return a negative value. This results in the skbpull function...

CVE-2024-35892

CVE-2024-35892 is a vulnerability in the Linux kernel’s network scheduler caused by improper use of the qdisclookup function. This function assumes the global RTNL lock is held, but in the qdisctreereducebacklog function, only a local queue lock is used. This mismatch creates a race condition tha...

CVE-2024-35957

The CVE-2024-35957 vuln in the Linux kernel/IOMMU VT-d path arises from probing code that tracked all probed devices in an rbtree by source ID, assuming uniqueness that VT-d does not guarantee. The fix, per the linked advisories, is to only track devices that have PCI ATS capabilities in the iomm...

CVE-2024-35941

This CVE (CVE-2024-35941) has concrete details in connected sources: a use-after-free in the Linux kernel net subsystem, due to skb->network_header overflow (u16) that makes skb_network_offset(skb) return a negative value. Consequently, __skb_pull() can move skb->data to memory outside skb-...

CVE-2024-35892

CVE-2024-35892 stems from a Linux kernel net/sched issue where qdisc_tree_reduce_backlog() was called with the qdisc lock held while RTNL was not held, triggering a lockdep splat due to unsafe RCU usage. The fix switches from qdisc_lookup() to qdisc_lookup_rcu() to safely dereference qdisc data u...
