kernel: Buffer overflow in drivers/xen/sys-hypervisor.c

A flaw was found in the Linux kernel. A buffer overflow vulnerability exists in the Xen hypervisor driver drivers/xen/sys-hypervisor.c. This flaw occurs because the HYPERVISORxenversionXENVERbuildid function returns a build ID that is not properly null-terminated. When the buildidshow function...

CVE-2026-45252

When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message to the userspace daemon to retrieve the list of extended attributes for a given file. The FUSE protocol requires the daemon to return a packed list of NUL-terminated strings. The fusefs kernel...

RLSA-2026:19365 Important: jq security update

jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data. You can use it to slice, filter, map, or transform structured data with the same ease that sed, awk, grep, or similar applications allow you to manipulate text. Security Fixes: jq: out-of-bounds read in...
