CVE-2026-45250

The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied list exceeds the capaci...

CVE-2026-45250

CVE-2026-45250 concerns a stack buffer overflow in the FreeBSD kernel arising from setcred(2). The unprivileged user can trigger a copyin into a fixed-size kernel-stack array before validating the number of supplementary groups, causing a stack overflow when the list is large. This allows an unpr...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkosf: fixed a possible incorrect match in nfosffind. nfosffind incorrectly returns true in case of a mismatch, which leads to copying uninitialized memory areas in nftosf. This can result in leaking stale kerne...

A flaw was discovered in the Linux kernel’s implementation of RDMA over InfiniBand. An attacker with a privileged local account can leak kernel stack information by issuing commands to the /dev/infiniband/rdmacm device node. Although this access is unlikely to reveal sensitive user information, i...
