Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Linux kernel's PCI sysfs interface (resourceN_resize attribute) lacked a capability check, so writing to it to change a PCI BAR's size was allowed without CAP_SYS_ADMIN, relying only on normal file access permissions. The source does not describe a specific exploit path. Affected kernel versions are listed as ranges by commit, starting at 91fa127794ac1c48069479b9d45eb4c7378c0e30; the source lists 6.1 as affected, with fixed versions 6.1.191, 6.6.160, 6.12.111 and 6.18.53 and later in each series. Upgrade to a fixed stable kernel release for your series. No workaround is given.
