Bisection points to a backported fix for https://nvd.nist.gov/vuln/detail/CVE-2023-52920: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ecc2aeeaa08a355d84d3ca9c3d2512399a194f29

It seems that this is a LTS kernel regression caused by the backport: https://lore.kernel.org/all/[email protected]/
