Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from an error handling path in the mctpinit function in the mctp driver that fails to free up routing resources,...

DEBIAN-CVE-2025-21972

In the Linux kernel, the following vulnerability has been resolved: net: mctp: unshare packets when reassembling Ensure that the fraglist used for reassembly isn't shared with other packets. This avoids incorrect reassembly when packets are cloned, and prevents a memory leak due to circular...

CVE-2025-21903

In the Linux kernel, the following vulnerability has been resolved: mctp i3c: handle NULL header address daddr can be NULL if there is no neighbour table entry present, in that case the tx packet should be dropped. saddr will usually be set by MCTP core, but check for NULL in case a packet is...

DEBIAN-CVE-2024-27418

In the Linux kernel, the following vulnerability has been resolved: net: mctp: take ownership of skb in mctplocaloutput Currently, mctplocaloutput only takes ownership of skb on success, and we may leak an skb if mctplocaloutput fails in specific states; the skb ownership isn't transferred until...

SUSE CVE-2023-3439

A flaw was found in the MCTP protocol in the Linux kernel. The function mctpunregister reclaims the device's relevant resource when a netcard detaches. However, a running routine may be unaware of this and cause the use-after-free of the mdev-addrs object, potentially leading to a denial of servi...
