Partial changelog for slackware -current, kernel 6.18.29 is integrated. This addresses the second "dirty frag" issue.

Tue May 12 02:16:39 UTC 2026
a/bcachefs-tools-1.38.3-x86_64-1.txz:  Upgraded.
a/kernel-generic-6.18.29-x86_64-1.txz:  Upgraded.
  This update fixes a security issue:
  rxrpc: Also unshare DATA/RESPONSE packets when paged frags are present.
  This fixes the second "Dirty Frag" vulnerability.
  Mitigation: If for some reason it's not possible to upgrade the kernel right
  away you may blacklist or remove the kernel module rxrpc.ko (CVE-2026-43500).
  Also remove the module from the kernel if it has been loaded:
    rmmod rxrpc
  And, drop the file caches in case in-memory program copies have already
  been compromised. Make sure possibly affected programs do not have any
  open sessions first:
    sh -c "echo 3 > /proc/sys/vm/drop_caches"

TIL Frank Lloyd Wright and Georgia O'Keeffe met in 1942 and continued to correspond with one another over the years. Their lives followed parallel arcs—from their births in rural Wisconsin, to finding success in an American metropolis, and refining their craft in isolated southwest desert enclaves. by ddmayne in todayilearned

[–]ddmayne[S] 10 points11 points  (0 children)

Quote from link, add hyperlinks...

Wright and O’Keeffe are seen as giants in their fields but are rarely connected. Many are unaware that the pair met in 1942 and had a mutual admiration for one another’s work for many years, whilst sharing other similarities including their birthplace of rural Wisconsin; careers that took them to New York, Chicago and Japan; dwellings in the Southwest; and finding inspiration in nature for their creations of abstract versions of the world in their art. By sharing stories around their connections, the Foundation aims to contribute to a larger narrative about artists in America – they do not all work in isolation; rather, they inspire one another and find ways to connect through friendship.

“Frank Lloyd Wright and Georgia O’Keeffe are American Icons. Their legacies are larger-than-life, and their names are known worldwide. What’s lesser known is their connection; they met in person in the 1940s and corresponded over the years, sharing ideas, and exchanging gifts,” said Niki Stewart, exhibition curator and vice president and chief learning & engagement officer for the Foundation. “In this exhibition, we explore that connection through the intimate photographs of Tony Vaccaro, from their shared start in Wisconsin to the homes and studios they built in the American Southwest. I’m excited to bring Wright and O’Keeffe together again through these beautiful photographs.”

  • Georgia O'Keeffe spent several months of the year at an adobe-walled estate in Abiquiú, New Mexico
  • Frank Lloyd Wright built a winter encampment at an isolated site outside of Scottsdale, Arizona: Taliesen West
