Linux kernel security vulnerabilities

A security vulnerability exists in the Linux kernel. It stems from the fact that seg6makeflowlabel fails to use skbgethashnet to obtain a network pointer. When an skb lacks both skb-dev and skb-sk, skbflowdissect triggers a warning due to the absence of a network pointer; this may result in null...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 3.8.6 and 3.9, as well as in version 3.9. It stems from improper handling of mount locking during automatic mounting; when mounts are propagated across user namespaces, a copy of the mount in the parent namespace gets locked...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.6.158, 6.12.111, and 6.18.53. This vulnerability arises because kfddbgtrapenable fails to revert enabled debug traps and related states when copying runtimeinfo into user space; as a result, trap states become inconsistent and...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 7.2. It arises because ioconnectbpfpopulate fills the CONNECT filter field only when addrlen is at least 28 bytes; however, IPv6 connection paths accept addresses with a SIN6LENRFC2133 value of 24 bytes. When addrlen is 24, the filter sees n...
