CVE-2023-53000 netlink: prevent potential spectre v1 gadgets

In the Linux kernel, the following vulnerability has been resolved: netlink: prevent potential spectre v1 gadgets Most netlink attributes are parsed and validated from nlavalidateparse or validatenla u16 type = nlatypenla; if type == 0 || type maxtype / error or continue / @type is then used as a...

CVE-2023-53000

CVE-2023-53000 is a Linux kernel vulnerability affecting the netlink attribute handling. The issue arises when the netlink attribute type (nla_type) is used as an index after validation, enabling a possible Spectre v1 gadget to leak kernel memory to a local attacker. The public description notes ...

CVE-2024-53212

CVE-2024-53212 is a Linux kernel vulnerability where a false positive warning in netlink extack could occur during dumps. The fix reworks the validation by using the netlink message header (nlh) instead of scanning skb->data, addressing a scenario where a dump is initiated but not completed du...

CVE-2024-53140 netlink: terminate outstanding dump on socket close

In the Linux kernel, the following vulnerability has been resolved: netlink: terminate outstanding dump on socket close Netlink supports iterative dumping of data. It provides the families the following ops: - start - optional kicks off the dumping process - dump - actual dump helper, keeps getti...

The vulnerability of the mptcp_pm_del_add_timer() function in the Linux operating system allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the mptcppmdeladdtimer function in the net/mptcp/pmnetlink.c module of the Linux operating system is related to the reutilization of previously freed memory due to competitive access to resources race condition. Exploiting this vulnerability could allow an attacker to...

CVE-2022-48784

CVE-2022-48784 : In the Linux kernel’s cfg80211 code, a race can occur during netlink owner interface destruction. The previous fix for a deadlock left a race when cfg80211_destroy_ifaces() runs while nl80211_netlink_notify() marks interfaces as nl_owner_dead. The issue arises from two loops: fir...
