Following yesterday's disclosure of the ssh-keysign-pwn vulnerability that [1]allows unprivileged users to read root-owned files , a slew of new stable kernel releases are out today to address this latest Linux security issue.

Today's release round-up is led by the [2]Linux 7.0.8 stable release that incorporates the patch from Linus Torvalds for ptrace as a "slightly saner" get_dumpable() logic. [3]This patch is what gets the ssh-keysign-pwn vulnerability.

In addition to Linux 7.0.8, [4]Linux 6.18.31 is out today for that latest Long Term Support version and with the only change being this security patch.

Similarly, [5]Linux 6.12.89 , [6]Linux 6.6.139 , [7]Linux 6.1.173 , [8]Linux 5.15.207 , and [9]Linux 5.10.256 are all out today as well for patching those older LTS kernels.
