Seven stable kernels for Saturday including two security fixes [LWN.net]

Greg Kroah-Hartman has announced the release of the 7.1.3, 6.18.38, 6.12.95, 6.6.144, 6.1.177, 5.15.211, and 5.10.260 stable kernels. Several kernels in this batch include a fix for a vulnerability introduced in the 6.0 kernel in IPv6 (CVE-2026-53362), which could allow an attacker to escape a container and gain root access.

There is also a fix for a use-after-free bug in KVM (CVE-2026-53359) that was introduced in the 2.6.36 kernel. As usual, each stable kernel includes a number of fixes throughout the tree. Users are advised to upgrade.

amdgpu_hmm_invalidate_gfx fix

If you use amdgpu with 7.1 or 6.18, you will probably want to apply "drm/amdgpu: fix check in amdgpu_hmm_invalidate_gfx" too, which fixes a NULL dereference - I kept running into it when playing video with mpv. The faulty patch ("drm/amdgpu: fix waiting for all submissions for userptrs") has been applied to 7.1 and 6.18 but the fix hasn't made it yet.

Thanks for the hint. I am currently compiling kernel 7.0.14 with some backported patches:

patching file net/ipv6/ip6_output.c
patching file net/ipv4/ip_output.c
patching file drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c
patching file drivers/gpu/drm/amd/amdgpu/amdgpu_hmm.c

kernel.org is still catching up

The kernel.org front page and announcements are messed up due to our primary mirror migration mishap, so please use tarballs from git.kernel.org until all sync is completed. You can still verify them using PGP signatures.

We've definitely learned some lessons from this. Thank you for being patient.
