CVE-2026-72379

A flaw was found in the Linux kernel's filesystem fs component. The vfstmpfile function, used for creating temporary files with OTMPFILE, did not properly verify if a caller's user and group IDs fsuid and fsgid were mapped within an idmapped mount. This oversight could allow a local user to creat...

UBUNTU-CVE-2026-72379

In the Linux kernel, the following vulnerability has been resolved: fs: refuse OTMPFILE creation with an unmapped fsuid or fsgid vfstmpfile never checked that the caller's fsuid and fsgid map into the filesystem. On an idmapped mount whose idmapping does not cover the caller's fsu,gid, the -tmpfi...
