Good morning. It's August 5th, 2026, and this is Linux Kernel Daily.
Today's activity is all late-cycle cleanup, four separate pulls from subsystem maintainers, and the common thread is hardening: memory safety and validation fixes that maintainers flagged as too important to sit until the next release.
The standout is in the integrity subsystem. Commit 5ff232d, from Lincoln Wallace, fixes an out-of-bounds read in IMA's xattr verification. The bug was subtle: mixing signed integers with size_t in a length check caused an underflow instead of a negative number, which let a truncated security dot IMA xattr slip past…
That same validation theme shows up in the vhost and vdpa pull. Michael Tsirkin's fixes tighten checks across the board: rejecting feature changes after a vhost-scsi endpoint is set up, validating scatterlist counts for T10 protection information, and bounding map allocations so a 32-bit system can't overflow on…
Two smaller but notable fixes round things out. Ingo Molnar's locking pull carries a fix from Keno Fischer closing a robust futex exit race, a narrow but real correctness fix in process teardown. And Anna Schumaker's NFS client pull fixes a reference-count leak…
